Somehow I seem to have got one functioning OneDrive installation or account on my PC, and a secondary phantom one. Every time I open Windows Explorer or browse for a file, a "Set up OneDrive" window pops up and invites me to sign in to an account, even though I am already signed into an account and OneDrive is working fine on that other instance.
How do I track down the real instance and the phantom, keep the real one and kill off the phantom? I'm guessing it may have something to do with having recently subscribed to Office 365, which came with a (new) OneDrive account.
I'm running Win 7 Professional 64-bit. Under Programs & Features in Control Panel, it only lists "Microsoft OneDrive" once, and there is no SkyDrive or older variant I can see. So it seems to be a single installation expecting to connect to multiple accounts perhaps (I'm guessing...?)
The only proposed solution to similar problems has been to disable OneDrive completely. I want OneDrive to work... I just don't want it to keep telling me it isn't working when it already is.
