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"

support emailed me saying this

Please close the launcher, then try the following and let me know if it helps:

  • Right-click on your Epic Games launcher desktop shortcut

  • Select “Properties”

  • In the line labeled “Target,” add the following to the very end (after the quotation mark): -SkipBuildPatchPrereq

  • It should look something like this: “C:\Program Files\Epic Games\Launcher\Portal\Binaries\Win64\EpicGamesLauncher.exe” -SkipBuildPatchPrereq

  • Click “Apply”

  • Double click the shortcut to run the launcher and try again

it didnt work for me, i got an error saying that the target path is invalid but maybe this works for others with this same problem

For people who get the " invalid target path " error, just add a space between the -SkipBuildPatchPrereq and the quotation mark

You can read more about this error here: http://help.epicgames.com/customer/portal/articles/2289966

If your system is up-to-date. Here's what I'd try next:

  • Completely uninstall everything related to Microsoft Visual Studio (VS, Redists, etc)

  • Completely uninstall anything related to the Unreal Engine

  • Reboot the system (to make sure everything is clean)

  • Re-install Unreal Engine + Redistributable's required to run it + Visual Studio

Beyond that, let's find the installer debug log. Can you share that? Follow the steps under: https://wiki.unrealengine.com/Troubleshooting_Launcher_Problems#I_am_unable_to_install_the_Launcher_for_Windows

we said we tried those, they didnt work at all.

My apologies. Revised the answer with the only thing that you can really do beyond waiting for more feedback from Epic. Sadly we're dealing with a custom install error so they're the only ones that can really figure out what's going on / what is being overlooked.

How are things going? Did this end up helping? Did you discover anything of significance in that log?

avatar image Tio Né Nov 28 '17 at 06:35 AM

Thanks, you helped me.

The original authors stopped responding to my questions. Can you fetch/share your log?

avatar image s4Ndw1ch Jun 22 '16 at 06:33 PM

How do I get the log?

avatar image mugsofpugs Jun 22 '16 at 09:08 PM

you go to C:\Users\"your name"\AppData\Local\EpicGamesLauncher\Saved\Logs to get to appdata you can open run command and put in %appdata% (takes you to roaming, just go back one) if you dont know how to get to run command look it up

avatar image Nolan.A Jun 22 '16 at 09:37 PM

My apologies for being slow in responding, I have exams and am very busy right now.

The log files are below, and uninstalling the drivers/reinstalling did not work.

I GOT THE ANSWER!!!! After literally hours of looking for a fix i finally found it, Okay so first your going to want to find your epic games launcher

Then your going to right click and go to properties once in properties your going to go to shortcut then go to the box that says target.

Once there type in -SkipBuildPatchPrereq making sure to have the space after the already existing target so it should look something like this

"C:\Games\Epic Games\Launcher\Portal\Binaries\Win32\EpicGamesLauncher.exe" -SkipBuildPatchPrereq

I really hoped that this helped you :)
