I can't install a new version of Adobe Reader because it can't uninstall the old version 7, and it says: "Contact your technical support group". Trying to uninstall the program manually does not work. Peter Kenyon
You will not be surprised to hear that uninstallation problems are covered in TechNotes on Adobe's website. One advises you to download the Microsoft Windows Installer Cleanup Utility, msicuu2.exe, which "removes enough information from the registry to reinstall Acrobat and restore the missing registry keys".
You can download msicuu2.exe here, where Microsoft warns: "If you use this utility, you may have to reinstall other programs. Caution is advised."
The topic also comes up frequently in Adobe's user-to-user help forum, and I'd recommend reading these messages.
The advice seems to be to use Windows' Add or Remove Programs utility, then run msicuu2.exe, and then, if necessary, delete all Adobe Reader files, folders and registry entries. You should create a restore point and back up the Registry before editing it manually. However, this may not always work. One user on the board comments: "If I ever get Adobe Reader off my PC, I will NEVER install it again! What a dumb program."
