Hi,
I know a lot of peoples asked this before, but my error code is different (and I tried a lot of fixes who didnt worked for me).
So I try to build a new C++ project and everytimes at 60% it crashed and says that :
Running C:/Program Files/Epic Games/UE_4.20/Engine/Binaries/DotNET/UnrealBuildTool.exe -projectfiles -project="C:/Users/planch2/Documents/Unreal Projects/MyProject/MyProject.uproject" -game -rocket -progress
Discovering modules, targets and source code for project...

Creating a blueprint project works.
I tried to reinstall the version, reinstall visual studio, i have every SDK (windowd 10 and 8.1), the UE4 installer on VS, community edition.
I verified the files of 4.20.
The error is “Illegal character in path”, but i don’t find any illegal characters! I just don’t understand…
Thanks in advice!
