I recently ran into an issue after a Microsoft automatic update with my DVD drive. So far nothing has resolved.
In trying to resolve, I ran into a post in Microsoft help site saying the IDU can cause this and providing instructions for correcting. My problem is that I cannot get the newer version of the PDU to install nor have I been able to get it uninstalled using add/remove programs. I get an error about multiple users being signed in. Have tried both normal and safe mode.
Is there a way to uninstall and how do I get around the install failure for multiple users signed on?
