Cubase hangs after Windows update

Since the Windows 10 spring update Cubase 8AI will not load. It starts to load but hangs on"Initializing: Video File Handling" and a window opens saying “Windows installer preparing to install”. Clicking “Cancel” does nothing and I have to close it with the task manager.
I’ve tried reinstalling Cubase, the eLicencer, and my UR242 driver.

I have the same issue. I installed a new version of CB AI 9 and activated it, but can’t load it because of the “Windows installer preparing to install” message.

I’ve just tried reinstalling the UR242 driver again but this time I uninstalled the previous one first. It did the trick.

Yep, this did the trick! Thanks.
