Need help please

I’m sorry if I’m posting this in the wrong category but I need help ! I recently did a reset of my computer and I’m not able to start any c++ project without running into compiler error. I’ve tried to run older and newer version of the unreal engine but I’m still running the same errors. I am using UE4 4.10.2 with visual studio 2015. Here’s my errors :

I’d say it looks like this is your problem.

PCH.Oravv_Game01.h.cpp(1) That is definitely a problem… it looks like a copying error, I’m pretty sure it needs to be something like “Oravv-Game01.h”

But, check your files.

If he says that the problem exists with ANY C++ project, maybe the compiler has a problem with the strange character(s) in the folder name?

First it says


C:\Users\?tienne\Documents\

Later it says


C:\Users\?%tienne\Documents\

I had a similar problem a while back. There were unicode characters (the letter ć) in my windows username, and all kind of strange compile issues were happening until i changed my username to ascii only.

Thanks guys ! I solved my problem ! It was a problem of permissions and prerequisites not downloading correctly ! The É in my name was causing the errors !
