Adobe automatic updater notified me that I had an update to install. I tried installing it, and got the following message:
Error 2331. Error loading library MSPATCHA or finding entry point ApplyPatchToFileByHandlesEx
I tried Microsoft Fixit, no change. I uninstalled Adobe Reader from Control Panel Add/Remove Software and downloaded Adobe Reader X again, and it won't install--I get the same Error 2331.
Download the Acrobat and Reader Cleaner tool. Use it to remove all traces of Reader. Then download the latest and greatest.
One more suggestion; can you try to download and run the MSI installer?
If you still get errors, please tell us your Windows version and service pack level.
