Need help with strange error

Hello,

I tried really hard to figure out how to get my engine back to work. Everytime I try to start the Engine, then everything seeems to work fine at first and then after a few seconds it crashes. The .log-File is reports about some missing dlls. I already uninstalled and then reinstalled Unreal but it didn’t help at all.

LogWindows: Failed to load ‘aqProf.dll’ (GetLastError=126)
LogWindows: File ‘aqProf.dll’ does not exist
LogWindows: Failed to load ‘VtuneApi.dll’ (GetLastError=193)
LogWindows: File ‘VtuneApi.dll’ does not exist
LogWindows: Failed to load ‘VtuneApi32e.dll’ (GetLastError=126)
LogWindows: File ‘VtuneApi32e.dll’ does not exist
LogConsoleResponse: Display: Failed to find resolution value strings in scalability ini. Falling back to default.
LogInit: Display: Running engine without a game

I couldn’t find a solution, even after hours of research. It’s very disappointing, since I started a new project recently and bought some quite expensive assets. Everything worked fine and I never had any problems. The Engine has always been stable, until today. Now nothing works anymore.

For further Information: The Error occured right after I tried to install a VR-Game Headset (Vive). My Laptop is quite good, so there aren’t any performance issues.

A complete reinstallation of Windows isn’t possible without losing too much of my content and setups, so this isn’t an option for me at all.

Some help would be very appreciated since I’m quite helpless now and desperately need a solution as soon as possible.

Thanks in advance
