My computer is running Windows XP Home Edition SP3. I downloaded the latest Adobe Reader version (v10.1) hoping to install it on the computer. When I went to Add/Remove Programs in Control Panel to remove my current Adobe Reader version (v.9.1), I encountered an error: "This patch could not be opened. Verify that the patch exists and that you can access it, or contact the application vendor to verify that this is a valid Windows installer patch package." What should I do?
Uninstalling Adobe Reader Version 9.1
This was known issues when installing and uninstalling adobe acrobat reader in Microsoft Windows Vista and Microsoft Windows 7. There were no exact or absolute solutions for this bug although there is some work around for this but it is not applicable to other. It may work for you but doesn’t work for the others. By the way you may try this:
Try to boot on safe mode and do the un-installation inside the safe mode shell.
If these procedures don’t work, try to find the adobe Uninstaller application in the Adobe Acrobat Reader folder under the Program Files folder and run it as administrator.
Manual deletion of the Acrobat Reader files may also work and clean the registry. But this is a risky move so make this option only if you are really familiar with registry cleaning and File dependency of the Acrobat Reader files.
