Can´t create a project

Hi,

I updated my engine to 4.17 and I cant update my old project aswell a new one.
If I try to create a complete new project I get this error:

ERROR: UBT ERROR: Failed to produce item: C:\Users\Shmann\Documents\Unreal Projects\sample\Binaries\Win64\UE4Editor-sample.dll

Does somebody know how to fix this?
