Please try pressing Ctrl+Alt+Del on your keyboard which should
bring up a menu. One of the options will be for Task Manager.
Select that option, and then select the Processes tab at the top of
the Task Manager. Locate any instances of Explorer.exe or
iexplore.exe, select them, and select End Task. This may cause your
start menu/taskbar to disappear, as well as your desktop, so have
the 1Password installer open and ready to go before attempting. You
can restart your computer from the 1Password installer once
installation has completed. If things don't work out, you can also
restart by pressing Ctrl+Alt+Del again and selecting the Log Off
I hope that helps. Should you have any other questions or
concerns, please feel free to ask.

I've tried several times to end prozesses with Ctrl+Alt+Del -
there is only the Explorer.exe (Internet Explorer isn't open!). I
shut down the explorer but the Error remains...
What can I do? Perhaps my whole system is corrupt?
I came here looking for a solution to this as well. I have two
fairly similar workstations where I have 1password syncing things.
One gets this error and even after killing everything possible in
task manager after a clean reboot, I can't automatically
Also manual updating has this problem too.
Aha. Found it. There were some IE processes owned by a user not
me, which I'm not sure what that's about after a clean reboot. Oh
Windows, you are such a mess.
