I have a nice clean MSI + transform for Adobe Reader 7.0.8. I deploy via Active Directory GPO, and it works wonderfully for about 10000 machines. Nice clean install on power up. No further issues.
But 900 machines have been *manually* upgraded to 7.0.9 or 8.x of Adobe reader.... on those machines, every time they reboot, the 7.0.8 MSI reattempts an installation and fails.
What are my options? I know it works if I have them manually deinstall Adobe Reader... but that's painful for so many computers.
