Re: [Vista] Unable to Install, or Uninstall, Adobe Reader
On a side note tangent, I don't have a Class key on my Vista 32bit Home Basic system.
HKEY_LOCAL_MACHINE\Software\Class
On my system I have
HKEY_LOCAL_MACHINE\Software\Classes |

said by auggy  :The Windows Installer may not run in Safe Mode. You are right. Windows Installer does not run in Safe Mode. I never knew programs could not be installed/uninstalled in Safe Mode.
I just tried to start the Windows Installer Service in Safe Mode and got a 1084 error. Also tried to uninstall Adobe Reader 9.1 and couldn't because Windows Installer wasn't running. |

said by auggy :The Windows Installer may not run in Safe Mode. However I was under the impression that you could not modify the permissions on the following registry key using regedit: HKEY_LOCAL_MACHINE\Software\Class\Interface\(46B89F5A-769D-4792-AD9A-E3755915CB3}\TypeLib
Do you get an "access denied" error trying to modify the permissions at that key? If so, does the same error occur in Safe Mode? I'm not even able to open the key, so it's not possible to change its permissions
Edit: I just rebooted and cofirmed that Windows Installer is always disabled in Safe Mode. |

You might try RegSeeker.
RegSeeker has a registry editor "Find in Registry" that allows you to delete keys. Maybe RegSeeker can bypass the premissions problem.

Before opening regedit.exe, can you right-click regedit.exe and select "Run as administrator".
Also, to rule out a problem with your user account, can you try another user account with administrator privileges (create one if necessary) and see if the same problems exist. |

I'm leary that getting rid of the key would leave me with a worse mess, with perhaps Adobe Reader 9.0 not working at all.
Also, I tried running RegEdit as Administrator and could still not open the key ... same error. |

Right-Click on the Adobe shortcut on the desktop> left-click on propatee>click on "advance">click in the box for Run as adminastrator.
Click "ok" then come out , and then try to uninstall.
If that doesn't work, download JV16powertool
here: »www.macecraft.com/
Install, then open,then SystemTools>Software Uninstall>find Adobe>checkmark it >Custom Uninstall> Find registry keys>Select all> delete > close> Restart
Now try to Install, if that doesn,t work I don,t know what else to do.
Hope that this helps

What I am guessing is that the uninstaller is hanging on this registry key, and there are probably more invalid keys after this one. After you delete this key, the next invalid key will stop the uninstaller. You will have to keep deleting each invalid key until they are all deleted. Then the uninstaller will be able to finish the uninstall.
To be safe, first export the registry key HKEY_LOCAL_MACHINE\Software\Class\Interface\(46B89F5A-769D-4792-AD9A-E3755915CB3}\TypeLib, or create a system restore point.
If something goes terribly wrong, then reinstall the exported registry key, or revert back to the previous restore point. |

Have you turned off UAC? If you have, turn it back on, reboot your computer and re-attempt the uninstallation of the old version of Adobe. Remember to "Run as Administrator" when you run the .exe for the new version of Adobe.
Worked for me once upon a time.

Sorry it took so long, but an error prevented me from even deleting the TypeLib key... "Error while deleting key"
At this point, I may wait for Windows 7 and perform a clean install. |

1 edit | If this were to happen to Me, at this point, I would:
Back-Up all critical data (or do a Full image backup of the OS partition to DVDRs, or to another HD with Acronis, or GHOST).
Perform a "Repair Install" of Vista.
See if that fixes the issue.
If not, (or if the Repair install should go badly), then I'd restore the OS partition from backup, or just do a Total Reinstall of Windows.

Was this a Window's error message, or a RegSeeker error?
Give RegSeeker a try, if you havn't already. |

For some reason, I'm unable to find the key using RegSeeker.
Edit: OK, found the key, and RegSeeker was unable to delete it either. |
