I am trying to uninstall Reader X in hopes that when I reinstall it some other issues will clear up. However, when clicking remove or update in Control Panel, I get the same result. "This patch package could not be opened...." Same message I have seen in a host of other postings.
Can I follow the same general instructions for manual uninstall that are in the knowledge base for Reader 8? Are there any additional steps/registry modifications? I am running XP/SP3.
You could try using the Windows Installer Cleanup Utility to remove all traces of any existing versions of Reader. This utility is no longer supported by Microsoft because it can conflict with Win 7, but you can still find it in sites like http://majorgeeks.com/download.php?det=4459
