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"

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 and make sure to add the space between the quotation and dash

Still having the issue. Ensured no other instances were running, and tried "Run as Admin".

What is your Operating System version? Does it always give you that same error or does something else happen?

Windows 8.1 Pro 64-bit. Same error every time. I've recorded the process here: https://youtu.be/xWMHLXmCtlk

That worked. Wonder if it's because I changed the default install location.

make sure you check that all instances of UE4/Launcher are closed out in the Task Manager before reopening the Launcher (since the Launcher by default remains in the system tray). PS. This is the only solution that has worked for us since it completely bypasses the Prereqs.

Simple fix. Find the launcher installed on your computer, right click on the application and Run as Administrator. Worked for me.

Apparently, restarting your computer may solve the issue too.

I had multiple Unreal Engine Versions installed. I removed the older ones as i figured that some files may conflict with each other. Then i verified the latest version and i had to run it with Administrative Prilviledges.

That was it for me.
