please have a look at this thread at or ask a new question there... 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. Hey, my computer won't start after accidently shutting down during windows update - the one that says 'Please do not turn off the computer'.
Ever since my last (successful) update, every time I boot up I receive the Adobe message "The computer must be restarted before updating can continue. "I've lived with this as all it requires is for "No" to be clicked on each startup (clicking "yes" simply re-boots the PC with the return of the message again), however, I now discover that when I try to run Adobe Updater, the same message comes up. 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. 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. When I click "update now" and download the update, I get a message "Another installation is in progress.For information on the Windows Registry Editor, see your Windows user guide or contact Microsoft Technical Support. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Run. If you click Yes, the computer is forced into a reboot, but the message returns. ISSUE: You may have a failed Adobe Reader 8 update.
