Adobe Reader 11.0.23 Update

Hello,

In my infrastructure, Adobe Reader 11.0.10 is installed. I'm planning to update the product, as the latest update available is 11.0.23. I'm using Ivanti for 3rd party application updates and through which I have downloaded the update 11.0.23. But its not getting installed on any of the test computers. Then I had tried to download the patches from adobe official site and downloaded 11.0.23 patch and installed but its failing with the below error.

"This patch package could not be opened.  Verify that the patch package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer patch package"

Can someone please help on this ? I need to update my current version rather than upgrading.

Regards

Vineeth
