Adobe Acrobat X Std/Pro updates

Hello,

I am trying to push Adobe Acrobat 10 updates with patch manager.

Unfortunately I can update the application only once, for example I can update from 10.0.0 to 10.1.9 successfully but later if I want to apply the latest update 10.1.10 the client won't receive the update.

Why is that? can anyone explain that to me?

Thank you.
