Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Hi Guys,

apparently this problem is a bit more complicated than it seems. A colleague of mine update to update 3 before i could stop him and uninstalling the update didn't work. It probably left some stuff behind. Also i needed to do a fresh install on a new machine and found no update 1 or 2 versions for download.

So here is the solution i found for both cases:

Unfortunately I could not find a way to install update 1 or 2 at this point. But at least it works. Hope this is useful for some of you.

Thanks @Infected_Post, this did solve the issue.

For anyone getting into trouble because of this issue in 4.11: the error message in 4.11 was slightly different: Error C4599 '/IC:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INCLUDE': command line argument number 248 does not match precompiled header

It did costs me quite some hours tracing this bugger down....

Thanks! Uninstalled Visual Studio 2015 Update 3, then reinstalled up to Version 2. Working correctly again!

avatar image OldUEProg Jul 05 '16 at 11:24 PM

I have followed both infected_Post's and Snake_Pliskin's advice, including restart after uninstalling and running the VisualStudioInstaller. When I reinstall, it looks like only Update 2 will be installed... But ultimately, when I start up, I see in VS About/Help that it is still Version 14.0.25420.01 Update 3.

Update 3 keeps sneaking in! Any ideas what I am doing wrong?

avatar image Snake.Pliskin Jul 06 '16 at 01:22 AM

You have to run the VisualStudioUninstaller tool. Try the newest release, and if that does not work, try the VisualStudioUninstaller Release 2. Then uninstall any thing related to VisualStudio (i.e. Windows SDK kits, Microsoft .NET Frameworks, Windows Phone Emulators, etc). Once everything is gone, REBOOT your PC. Download the Visual Studio 2015 community ISO, mount the ISO or download the Visual Studio 2015 community webinstaller. Open a administrative command prompt, go to the folder where you have saved the webinstaller at or the root folder if its the ISO Basicly you want to be in the same folder as the file vs_community_ENU.exe is in. Most importantly, copy+paste the following into the command prompt, all as one line:

vs_community_ENU.exe /OverrideFeedURI http://download.microsoft.com/download/0/6/B/06BB0C5C-C767-4250-91DA-AB463377597E/20160405.3/enu/feed.xml

During install it will say "VS2015 with Updates" and once finished installing the VS about page will look like this: VS2015 Update 2

I'm not having any luck uninstalling and reinstalling, either. I'm not sure what makes it not work on my computer. Maybe it has something to do with Windows 10...

avatar image Snake.Pliskin Jul 06 '16 at 03:07 AM

I am running Win10 Pro x64. Did you use the VisualStudioUninstaller tool? Did you follow the directions for it?

  1. Extract TotalUninstaller.zip

  2. Open an administrator command prompt

  3. Execute Setup.ForcedUninstall.exe

  4. Type 'Y' to uninstall.

Personally the newest release of the tool did not work for me, where as the older version 1.1 did work for me. Get it here-> VisualStudioUninstaller 1.1

"Then uninstall any thing related to VisualStudio (i.e. Windows SDK kits, Microsoft .NET Frameworks, Windows Phone Emulators, etc). Once everything is gone, REBOOT your PC." " Open a administrative command prompt, go to the folder where you have saved the VS2015 setup at." copy+Paste the following into the command prompt:

vs_community_ENU.exe /OverrideFeedURI http://download.microsoft.com/download/0/6/B/06BB0C5C-C767-4250-91DA-AB463377597E/20160405.3/enu/feed.xml

alt text

IMPORTANT: If at any time later, you have to make any changes to what features are installed for VS2015 AFTER the initial install of VS2015.2. You MUST do so by using the same command used for the initial install. If you do not use that command, then setup will AUTOMATICLY download and install the latest update (3) for VS2015!!!

I did use the VisualStudioUninstaller tool. I used the newest version. When it uninstalled everything, I kept getting one package return with an exit code of like 1163 (or something like that). I'm assuming that was a failure code, because when I just ran the tool again, I got everything with exit code 0. I also did not realize that I needed to run the update command with the same parameters. I'm trying to offline visual studio installer now, and I'll report on how that goes after.

When you did the Visual Studio 2015 Update 2 installation, did you select the default installation or a custom one?

avatar image OldUEProg Jul 06 '16 at 03:45 AM

I appreciate the details, Snake, but it just isn't working for me. I uninstalled everything that looks like a VS artifact program, ran both VisualStudioInstaller 4 (the latest) and 2, and deleted all folders I could think of that VS might access. I rebooted multiple times. The last attempt I downloaded the ISO, disconnected from the internet (just in case), opened an administrative command window, ran the installer with the command line params and selected to install only Update 2 and C++. Once again, on probably my eighth attempt, I still would up with Update 3 installed...

There's some kind of Update 3 artifact left on this system that keeps getting used, but it isn't anything obvious. Something in Windows\Temp maybe?

avatar image Justin.Dooley Jul 06 '16 at 09:14 PM

Same here Today has been spent installing and uninstalling VS.

avatar image Snake.Pliskin Jul 07 '16 at 02:44 PM

No, you HAVE to be connected to the internet for it to work. That URL in the setup switch is the location where setup will download the files for Update 2 from. If setup can not connect to that URL, by default, it uses the Update 3 files it already has.

I have the same problem, I have updated my Visual studio 2015 community to Visual studio 2015 enterprise, how can I solved it

avatar image Tim C ♦♦ STAFF Aug 23 '16 at 06:08 PM

Hi Waris_Developer,

The latest hotfix for version 4.12 should work fine with Visual Studio 2015 Update 3, and there is an optional update for 4.11 that provides support for Update 3 in that version as well. If you are using version 4.10 or earlier, then Visual Studio 2015 Update 3 will not work with the Engine.

Hi everyone,

We have released the 4.12.5 Hotfix today. Part of this Hotfix is the inclusion of our fix to allow the Engine to work with Visual Studio 2015 Update 3. If you have Update 3 installed, you can update UE4 to 4.12.5 and should no longer have any problems when compiling code. If you do, please let us know with a new post here..

Unfortunately this Hotfix does not affect previous versions of the Engine, so if you are still using 4.10 or 4.11, you will need to either merge the fix for Update 3 into a source code version of the Engine and build it, or stay on Visual Studio 2015 Update 2.

Hi everyone,

I just wanted to pop in here real quick to let you know that we do not yet officially support Update 3 for Visual Studio. Our goal is to have support for new VS updates by the time they are officially released (Release Candidate versions are not official final release versions). Sometimes we are able to get that support into the Engine early, but as of right now it is not in place.

I brought this up with the individual who will be responsible for making sure support for Update 3 is added to the Engine. He has not done any testing on this yet, but he believes it should be possible to correct this issue by opening the WindowsPlatformCompilerSetup.h file in source code (this won't correct it for the binary version of the Engine, unfortunately), and remove 4599 from the table of warnings at the top. Then add #pragma warning(disable : 4599) below the list. It is possible that this may not work since the warning is coming from command line arguments instead of source, but it's the first thing he is going to try when he starts working on support for Update 3. He also said that he does not believe this edit will have any adverse affect on your game code generation, but stressed again that he has not done any testing yet.

For now we recommend sticking with Visual Studio 2015 Update 2.

Or you can also add the lines:

 #pragma warning(disable : 4599)
 #include "Engine.h"
 #pragma warning(pop)

avatar image sklug Jul 03 '16 at 02:12 PM

I applied this workaround and it didn't completely solve it for me with 4.12.4. I followed the same instructions for warning 4605 as above and that solved it however.

avatar image TriNityGER Jul 05 '16 at 05:22 AM

Any timeframe for official Update 3 support?

avatar image Tim C ♦♦ STAFF Jul 05 '16 at 04:01 PM

Hi TriNityGER,

We have a fix in place for anyone using the source code version of the Engine available from GitHub. You can get that fix here, and it should work fine in 4.10 and 4.11 as well. Unfortunately anyone using the Binary version of the Engine installed through the Launcher will still run into problems when using VS 2015 Update 3. We have logged ticket UE-32790 to track the issue with the Binary version of the Engine.

Tim

avatar image benoithudson Jul 05 '16 at 03:42 PM

I just added the line

 #pragma warning(disable : 4599 4605)

after the big block of #pragma warning(error:...) up top. Order matters.

It seems to work fine in my setting (making editor plugins to support a production pipeline).

I had to make sure that my configuration was all x64 which my UE4 was NOT so I added the configuration, x64 platform there... ( Build -> Configuration Manager)... added x64 from Win32 Settings alt text

I also searched for the WindowsPlatformCompilerSetup.h using Ctrl+Shift+F type in the name , tell it to search for entire Solution, then go down to line 34 or so and insert #pragma warning(disable : 4599)

Then I recompiled UE4 and then my class and it worked for Service Pack 3 ( It added the C++ class to the Content Browser)

NOTE: Before that, in the main toolbar, I only had Build button, the compile button was not present...

It's because of the following change in VS 2015 RC3:

"When using PCH files, mismatched -I include directories to the compiler between -Yc and -Yu compilations will now produce a new warning. C4599"

This is getting thrown as an error, even though it looks like the build tool isn't setting /WX. You cannot use the normal suppression of errors via the project or solution file because UE4 isn't actually built by VS and you can't use the pragma warning directives in the cpp files to suppress the error either. Attempting to uninstall the RC3 update leaves VS in a state where it continually crashes on startup and I cannot seem to find an installer from MS that doesn't already have RC3 included so I can do a fresh reinstall.

Unfortunately, at the moment, I don't have a solution, only the cause. I think I'm going to have to grab source from github and see if I can fix it manually but that's kinda a PITA when I really just want to fiddle around with my game.

There's a link on there that claims to be VS2015.2 but it is mislabeled. I downloaded that yesterday as an ISO and it installed RC3.

avatar image snidersh Jun 14 '16 at 05:35 PM

Success! I had to disconnect from the internet before installing or it would automatically pull down the RC3 update. Let's hope they fix the C4599 error soon.

avatar image pyropace Jun 15 '16 at 12:11 AM

Did you uninstall VS completely first ?

avatar image Snake.Pliskin Jun 15 '16 at 12:49 AM

I did try to uninstall RC3 and tried to reinstall Update 2 but had issues. I had to use this utility to remove all traces of visual studio so I can do a new clean install of VS2015.2.
Use this as a last resort https://github.com/Microsoft/VisualStudioUninstaller

avatar image snidersh Jun 15 '16 at 01:14 AM

Just uninstalling RC3 left VS in a very bad state. I had to completely uninstall VS, then install the version with no updates and then install Update 2. Even after that, for some reason VC++ was in a bad state and I had to do a complete repair. After all of that, I am finally back at Update 2 and everything works again.

avatar image Snake.Pliskin Jun 16 '16 at 05:44 AM

I thought this may fix. This is what I did and I was able to compile without errors (though custom plug ins are still not working for me for all but development editor builds)

  1. Install VS2015 (with C++, common tools, Win 10 SDK)

  2. Installed Win 8.1 SDK from the standalone installer (separate from VS2015, do NOT add Win 8.1 SDK feature from the VS2015 setup). Get it at https://developer.microsoft.com/en-us/windows/downloads/windows-8-1-sdk

avatar image iaanus Jun 16 '16 at 07:28 AM

No wonders it works like that. The problem arises only when you install Visual Studio 2015 Update 3 RC, which, at the moment of writing, comes in a separate installer. Your procedure will install updates up to Update 2.

Even settings bUseSharedPCHs = false; in BuildConfiguration.cs is not enough. I'm giving up and uninstall/reinstall Visual Studio. My advice is to NOT install Update 3RC (nor Update 3 when it's released) until we have a proper fix.

How to: Install a Specific Release of Visual Studio (i.e. Visual Studio 2015 with only the original Update 2 without any further Update 2-era updates or Update 3))

  1. If you have VS2015 with Update 3, you must completely uninstall it and reboot your PC. (You may have to use the VisualStudioUninstaller Release 2 worked for me where the latest did not)

  2. Download the VS2015 with Update 3 websetup from VisualStudio.com (example: vs_community_ENU.exe) It does not matter that it is the Update 3, we are going to force it to install Update 2 and not 3 in the next step

  3. "then append the .exe file with additional command-line parameters". For the VS2015 community edition it would be (enter the following all as one line from a administrative command prompt):

vs_community_ENU.exe /OverrideFeedURI http://download.microsoft.com/download/0/6/B/06BB0C5C-C767-4250-91DA-AB463377597E/20160405.3/enu/feed.xml

Now that Microsoft has officially released VS2015 update 3 (no longer RC 3). I went ahead and installed it and UE 4.12 will not compile at all with it. It was working just fine with update 2!! Once the update had finished installing, I did go back to modify the features and I noticed that update 3 removed some of the C++ features. After reinstalling those features, VS2015 update 3 still will NOT build UE 4.12.

I got fed up and said I'm going back to VS2013, so I did this:

  1. Run the command GenerateProjectFiles.bat -2013

  2. Open the project with VS2013

  3. Rebuild the project

And guess what, IT WORKS! Not a single error!

The only problem is that the compiled files are not compatible with the launcher game. They will work in a debugging session in VS.

VS2015 has more bugs then Windows 3.1! Epic before warned, you guys are going to see a lot more people complaining about this issue now that this is a official update to VS2015.

The fact that a software doesn't do what you want right out of the box does not mean it has "bugs". Maybe your expectation are just unrealistic. The issues are caused by stricter VS2015 U3 diagnostics, which I would describe as "features" not "bugs", that are raising warnings about some shady compilation techniques used by Unreal. Just give Epic some time, I'm pretty sure with just a few tweaks Unreal will play fairly with VS2015 U3.

avatar image Snake.Pliskin Jun 28 '16 at 07:47 PM

Update: It does compile and will run in a debugging session in VS, but the files are not compatible with the launcher game (when using UT).

Please don't take this the wrong way, I'm not trying to argue with you, I just want to illustrate why I said VS2015 is bugged:

"my expectation are just unrealistic"? You have no idea how much trouble VS2015 has given me. At first I had the "Roslyn package failed to load" that would prevent any file from being opened with VS2015. There is a active bug with Microsoft about this.https://connect.microsoft.com/VisualStudio/feedback/details/1342588/roslyn-package-failed-to-load-correctly-installing-2015rc Even a txt file would crash VS2015. So no its not just Unreal that is the issue. Doing a repair did not fix, nor did uninstall and reinstall. I have had to completely wipe out my pc in hopes that VS2015 will work as it should. And even after a clean install, I have still had some issues with it. Finally got it working, only to have Update 3 break it. I have never had soo many problems and experienced VS crashing so often with any of the prior versions, dating back to Visual Studio.NET.

In VCToolChain.cs, line 250:

 // @todo SharedPCH: Disable warning about PCH defines not matching .cpp defines.  We "cheat" these defines a little`
 // bit to make shared PCHs work.  But it's totally safe.  Trust us.
 Arguments.Append(" /wd4651");

It seems that Visual Studio 2015 is no longer trusting you, Epic. In fact even persevering in the "cheat" by adding

 Arguments.Append(" /wd4605");
 Arguments.Append(" /wd4651");

does not seem to solve the problem. Please fix.
