While trying to start a C++ fts project error message pops up thats says: Running D:/Unreal Engine/UE_4.21/Engine/Binaries/DotNET/UnrealBuildTool.exe -projectfiles -project=“D:/Unreal Game c++/SMOffV1/SMOffV1.uproject” -game -rocket -progress
C:\Users\AppData\Roaming\Unreal Engine\UnrealBuildTool\BuildConfiguration.xml(4): error: There are multiple root elements. Line 4, position 3.
ERROR: Failed to properly read XML file : C:\Users\AppData\Roaming\Unreal Engine\UnrealBuildTool\BuildConfiguration.xml
How do I fix this problem?
Thanks in advance 
Hi @wummoFTW , to be honest, I haven’t seen this build error before… and I have seen a lot of them. It will be hard to diagnose without more information though. If the following suggestions aren’t helpful let me know, I don’t know how much programming experience you have. =]
Firstly, are you building the engine from source or did you install the engine?
Second, how did you create the project?
Third, are you using Visual Studio 2017 or VSCode?
Fourth, are you building the editor configuration? (Development Editor as opposed to development game)
Fifth, is your IDE building in the 64 bit?
Finally, if you are building from source can you try just building the unreal build tool?
