I have the Master Collection of CS3, Adobe Updater 5, Windows XP. Updates have installed in the past, but the Update window shows no updates are available when it pops up. Yes, I run as the administrator.
Same problem as posted here:
No answer there except to change the preferences, which I can't get to.
I just fixed this problem on an old PC of mine. The problem looks like it is caused by the Adobe Updater stuffing up when you do actually need an update. To fix:
1. Close any Adobe applications
2. Open Task Manager (you may need to check the "Show processes from all users")
3. Highlight and hit End Process for anything called AdobeUpdater.exe and AdobeARM.exe, confirm you definitely want to terminate the process.
4. Open an Adobe program
5. Check for updates from within the program.
Once I did this it downloaded and installed the update fine. The next time I rebooted and got the correct screen where I can set preferences to only check once a week and it all seems to work fine now.
(I only use Adobe Reader but I'm guessing as the symptoms are exactly the same the answer is likely to be exactly the same, maybe if you have multiple apps installed you may need to do the check from every app until you find the one with the stuck update).
Hope this helps others as I've not seen anyone post a fix even though this has been around since at least 2009!
