Another installation is in progress; you must complete that installation before continuing this one -- NO other installing IS in progress and using Windows 8.
A couple plug-ins need to be updated. When I click "update now" and download the update, I get a message "Another installation is in progress. You must complete that installation before continuing this one." I am using Windows 8. There is NOTHING else being downloaded at this time. I have restarted and that doesn't help This has been going on for several days.
The plug-ins that I'm trying to update are QuickTime and Google Earth. I was also unable to update my printer software.
I need simple instructions on how to correct his. I searched and see that this has been a problem for others but can't find a simple fix that isn't way beyond my basic knowledge.

Figured out the solution on my own. If this should happen to you, I opened Windows Update Troubleshooter (Windows 8), and it corrected the problem in order for me to update all plug-ins. Restarted and all was fine!

hello mpitt, this sounds more like a problem of your operating system - here on a forum specialised on support for the firefox browser we might not be the right people to come up with a solution for this kind of issue...
please have a look at this thread at http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/another-installation-is-in-progress-you-must/24c41516-0e6f-4bab-80a3-d1aa54f128d0 or ask a new question there...
Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
