I installed the Unreal Engine on a new PC and noticed that this time it was installed in C:\Program Files (x86), even though it is an x64 system. On my previous system, it was installed (by default) in C:\Program Files.
It seems to me that, all of a sudden, I’m now using the a different version of the engine(?). I tried to reinstall, but I cannot find an x64 launcher. What is this all about? Did the location change? Is the detection of x64 not working? Are there two different versions of the engine for Windows (x86, x64)?
After recreating the visual studio project files for a test project I created on the previous PC, I keep getting an error that “Epic” cannot be found (when trying to rebuild the project, right at the start), and that seems to be a path-related error … I have no idea what this is all about…
Log of the second error, which may be a follow-up because the engine is installed in “Program Files (x86)” is:
“\Epic” kann syntaktisch an dieser Stelle nicht verarbeitet werden. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.MakeFile.Targets(42,5): error MSB3073: Der Befehl ““C:\Program Files (x86)\Epic Games\4.10\Engine\Build\BatchFiles\Rebuild.bat” TwinStickShooterEditor Win64 Development “D:\Projects\Unreal\TwinStickShooter\TwinStickShooter.uproject” -rocket -waitmutex -2015” wurde mit dem Code 255 beendet.
This is German for (roughly) “\Epic” cannot be syntactically processed at this position. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.MakeFile.Targets(42,5): error MSB3073: The command ““C:\Program Files (x86)\Epic Games\4.10\Engine\Build\BatchFiles\Rebuild.bat” TwinStickShooterEditor Win64 Development “D:\Projects\Unreal\TwinStickShooter\TwinStickShooter.uproject” -rocket -waitmutex -2015” exited with code 255.
It seems that the “(x86)” in “C:\Program Files (x86)\Epic Games\4.10\Engine\Build\BatchFiles\Rebuild.bat” somehow messes up the command, because the brackets have a special meaning. Note that there are quotation marks around the Rebuild.bat filename, so the spaces in the file name should not be the problem.
I will reinstall and manually change the directory of the launcher to somewhere on D:, but maybe you could have a look at this problem.
After manually installing the Unreal Launcher and the Engine on D:, the visual studio build is working fine. So the “Program Files (x86)”-default is causing the problem.
Thank you for the information. There have been recent changes to the way the launcher is downloaded and installed in order to have 32-bit compatibility. Your system should have the 64-bit launcher installed, it is just installed in the 32-bit directory. This is a known issue.
As for the other issues you reported, that is being investigated.
Actually, according to the upper post, it is the x64 version, it is just installing to the wrong folder.
Unfortunately, you cannot change the folder to C:\Program Files, because it will automatically change back to C:\Program Files (x86). Until this is fixed, just install it somewhere else, like C:\Games\Epic or whatever :-).
I see. Thank you. I’ve just downloaded the source and compiled it. Everything seems to work now. I’ll use your solution next time I choose the installer version.

Hi ; I tried everything … installing it in different folder, installing in different drive. But still not working, it gets installed in to win32 by default and my system is 64 bit … ““D:\VR\Epic Games\Launcher\Portal\Binaries\Win32\EpicGamesLauncher.exe”” and the launcher doesn’t work, it just says “Please wait”. any other method to install?
