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"

Failure to Launch ("Installing DirectX" then "Removing Backup Files")

Hello, I just bought a subscription today and am faced with this problem when running the Unreal Engine executable. The install process gets to "Installing DirectX" freezes then "Removing Backup Files". The 4.x folder is not downloaded by this point and the launcher doesn't show up. No crash messages accompany the lack of a launcher either. Thoughts?

Sorry to hear you are having install issues. We can probably help you more if you post your installer logs. To get the installer to generate logs you can try the steps outlined in the MSI (Windows only) installation issues section of this thread: Link

Or you could follow these steps:

Place the msi on the root of C drive Start a cmd prompt as administrator (Start-> type cmd in the search bar and right click cmd.exe and select Run as Administrator) You should see a command prompt that says Administrator in the title bar Enter the following command(be sure to replace 'UnrealEngineInstaller.msi' with the actual msi file name):

msiexec /i C:\UnrealEngineInstaller.msi /L*V C:\UnrealEngineInstallerLog.txt

Once you post the log we can try to pinpoint the issue you are having and try to get you past it.

The generated log is 1,969 KB, and I can't upload it due to it being over the max allowed size.

EDIT: Nevermind here it is:

According to the log file you provided, it appears that your install completed successfully:

 [10:41:23:874]: Product: Unreal Engine -- Installation completed successfully.

  1. Does this folder exist? C:\Program Files\Unreal Engine\Launcher

  2. Do you have an Unreal Engine shortcut on your desktop or in your start menu(Start->All Programs)? If so, what happens when you try to launch Unreal Engine using the shortcuts?

  3. Would you please provide us with your newest UnrealEngineLauncher.log. According to this Link, you can find the logs in the following location(be sure to change USER.NAME to your user):


  4. Do you have any files with the .dmp extension in this folder? If so, can you zip those up and post them?


avatar image Tinnyton May 21 '14 at 09:22 PM
  1. Yes

  2. Yes, in both places. When launching it from either place, the process shows up in my task manager for about 5 seconds then disappears but nothing else (no actual launcher nor an error message).

Any word on a fix yet?

Still trying to pinpoint why some users are seeing this issue. I don't have an answer yet but one user did get past the issues by installing some Windows updates. More info here: https://answers.unrealengine.com/questions/47755/unrealenginelauncherexe-crashes.html

Hi Tinnyton,

I'm sorry you're having this issue. Are you trying to install UE4 on your main drive? Also, what are your PC specs, specifically your graphics card?

avatar image Tinnyton May 17 '14 at 07:31 PM


I've tried installing to the following locations:


C:\Program Files\

C:\Program Files (x86)\

My Specs:

Thanks for the help!

Also, how would I go about getting 3 days added back to my subscription?

Any word on what could be causing the issue?

I'm not exactly sure what is causing it, so I am going to discuss this with one of the developers. I hope to have a suggestion for you soon.

I'm having the same problem, months later. The installation goes normally until it tries to install DirectX. After that, There is a brief message: "Removing backup files" then the install closes. A desktop shortcut is made that doesn't open due to ERROR 0x000007b.
Files are put into the Program Files folder but I'm unsure if everything is there.
