Created an admin share. Ran the 9.1.2 msp file and it patch successfully. When I go to run the newly patched acroread.msi, I get the following error:
Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.
The version on the PC I am trying to run it on is 9.1.1 and I confirmed that to be the case. Anybody have any thoughts or ideas as to how I should proceed?
When you deploy the application through group policy and add the new application, under the upgrade tab you should add the older version (or remove it and re add it if it's already there). This gives you the opportunity to make sure that you select the checkbox to uninstall the previous version prior to installing the new one (as opposed to doing an in place upgrade).
It takes a little longer to install but should work.
This being said, Adobe has some issues with their latest round of patches:http://forums.adobe.com/message/2040285#2040285
