Renaming my company files on a so there were no spaces in it resolved my issue. 

The first error in the windows event log :

An unexpected error has occured in "QuickBooks Desktop Pro":
Got unexpected error 5 in call to NetShareGetInfo for path \\path to my QuickBooks file. 

Waiting for Microsoft is not an option for me.
