no save file, no game start?

Why is the documents folder inside onedrive? 

This message means that the game does not have permissions to touch your documents folder, this happens when you set the folder to be read only or a antivirus is preventing it from touching it or another program is trying to use the same folder at the same time as the game.

thank you very much.

I have deactivated OneDrive. Reinstalled Oni. Now it s working.
