I am getting similar errors when trying to Log in.
There is an error Dialog that pops up on Login. If I close the Dialog QB closes.
But If the Dialog Stays open QB works normally.
I have 8 installations (Win 10) and only 3 of these have the problem. ( Just added one today after we upgraded him to 16G RAM)
Reinstalling had no effect.
Type of user permissions no effect.
This is a problem because I cannot login to manage the Backups.
