Same behavior on my machine. I didn’t start from scratch but updated Git to release, ran the Setup.bat (running prerequisites) and GenerateProjectFiles and rebuilt on VS2015 without errors.

Resolved the issue by saving the project elsewhere (not within the user directory path). Usernames with special characters seem to cause problems.

I didn’t have any special characters on my path, nor anything different on how the previous version worked (I’m not sure if I ran 4.9, but my version was at least 4.8). I’m proceeding to copy the project to different location (to avoid user-specific permissions) and retry.

Testing again from scratch; I’m assuming I have something legacy messing this up somehow…

My problems went away when starting from scratch apparently as well; saving in user specific directory but without any special chars.
