Subrato,
first i try to apply the 11.0.03-msp into an 11.0.02-AIP: failed
Then I create a new AIP of 11.0.00-MSI and applied 11.0.03-msp: Success
After that i run msiexec /i <aip\Acroread.msi TRANSFORMS=Acro.mst on a machine with a GPO-installation of 11.0.02. This failed with "Another version..."
The same result when I doubleclick the 11.0.03-msp on that machine.
Anyway, now I know how to handle it in the future.
Thanks for helping
H.
