Error 1402:Could not open key: HKEY_LOCAL_MACHINE32\...

I am trying very hard to Uninstall Adobe Reader 9.1.0 but I am continually stopped by this error which says I have insufficient access rights to delete the Registry entry. I was originally trying to install the latest upgrade.

1) I have looked through the Knowledge Base and NO solutions are there.

2) I have scoured the Forums and no one has found a solution.

3) From searching these places and the web, it appears that many people have the same problem.

4) To this point Adobe's Support has been noting short of utterly Abysmal. All they say to do is: go to Control Panel and uninstall it. (OR ask for a Support Contract which is unacceptable for this issue)

5) I can only hope that nothing goes wrong with my currently installed version because it is very apparent that I will never be able re-install or upgrade it.

6) BTW, I have tried setting the Permissions on this key in the Registry ( with backups of course) for SYSTEM and ADMINISTRATORS to FULL and that does not help.

So Adobe Support, if by freak luck, you may be reading this,  I would really like you to figure this out and provide a working solution.

Any script which will clean out Adobe Reader completely would be great.

For the record I am running Vista 64bit SP2 on a system with a Quad9550 cpu and 8BG of ram.

I find it curious that the key mentioned is "....MACHINE32\...."  but there are NO entries at all like that in my Registry, only ...MACHINE\...  That may have something to do with this issue.

PLEASE, thanks in advance for anyone's advice but I want to hear only from people who have discovered a proven working solution: i.e no guess work.

Thanks
