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.
Try the offline installer from http://get.adobe.com/reader/enterprise/
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.
