I ran into a sticky situation while trying to apply a second patch to an application but failed, instead getting an error. The actual scenario was that my product was version 2.0 which was already patched with version 2.1, applying patch 2.2 failed but when patched directly with 2.2, it upgraded successfully.
This is the upgrade error I received while patching;
"The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be updated exists on your computer and that you have the correct upgrade patch."
Notice the error number is missing, that a fail to installshield.
Among other,s the reason why this error occurs is because the application to upgrade is either not installed, the Upgrade code has changed or the previous patch Package code may be similar to the new patch. In my case I discovered that the patch 2.1 was somehow changing the upgrade code making it impossible for the 2.2 patch to install.
My solution to this issue was to change the Transform Filter Settings on the previous packages page. I changed the ‘Match Upgrade Code’ setting to “NO” and left the “Match Product Code” setting as ‘YES’ this would make sure that the patch only upgrades the product version it is supposed to leaving out the upgrade code validation. This may be a crude method but it fixed my issue in the nick of time.
Here is an image to demonstrate.
