Error Deploying Acrobat via AD in Server 2008 R2

Hi Folks,

We've recently migrated all our Active Directory domain controllers from Windows Server 2003 to Server 2008 R2. We previously deployed all major apps (including a number of Adobe products) using group policy deployment via msi's which worked great.

Now, in attempting to add ANY Adobe msi installer package in Server 2008 R2 to a group policy we get an error stating:

"Add operation failed. Unable to extract deployment information from the package. Run validation on the package to ensure that the package is correct."

This happens with msi's for Acrobat Standard 9.0.0, Acrobat Pro 9.0, Acrobat Reader 9.1 & 9.3 & Flash Player 9.

ALL other deployed applications work fine on Server 2008 R2 - the problem affects all of our Adobe products and none of our non-Adobe products.

Any ideas?

Thanks,

Shaun K.
