Ok, so:

  1. Replace %PROGRAMFILES% with %PROGRAMFILES(x86)% in the npl config and see if that resolves correctly.
  2. Create projects in a regular folder, not on desktop. I’ve seen Windows Defender blocking write access to files in Desktop already, and this may very well be the case.
  3. Try creating a regular MG project on Deskto and opening its .mgcb.
