How to Update Acrobat X with error 1635? (Microsoft Fix It and repeated uninstalls unsuccessful)

Question

Hello,
I recently replaced Acrobat 9 Professional with Acrobat X (standard).  One of the reasons I did so was because I always received an error 1635 message when attempting to update Acrobat 9 Professional, which annoyed me, and which I thought I could eliminate with a fresh install (not an update) of the new Acrobat X Standard program.  However, I find that I cannot update Acrobat X either, as I still get the same "error 1635" message when attempting an update.
I have uninstalled and reinstalled the program several times, but receive the same error message when attempting to update.  I then used Revo Uninstaller, no difference.  I have run the Microsoft fix it tool, again, no difference.  Despite everything I've done, I continue to receive the "error 1635" message every time I attempt to update the Acrobat X program.  Very frustrating!
Can anyone help identify the issue and suggest a fix?  I imagine this issue is the result of a bad registry key but I have no way of identifying which key (or keys) to delete.
Thanks in advance for any help!

Assuming you have tried everything including using the uninstaller tool then it looks like you will need to take a risk by either deleting the registry key ending with 50 or try to use CCleaner which will match the product and remove the registry key for you automatically.
With CCleaner you have the option to delete only the Adobe Key rather than other redundant keys that are always there because of the way how Windows works.  I use Ccleaner regularly but I consider myself quite good at PC Maintenance and Repair so it is up to you to take the risk.
Do you know anybody whose hobby is to fix PCs?  Perhaps they can remove the necessary keys from the registry.
