I have an Install script CA that I want to run only under a select set of conditions. And I'm having a devil of a time figuring our how to "code" the conditions correctly.
I'm wondering if I might ask for help from those more experienced in these issues.
I only want my CA to run if performing a minor upgrade. NOT during a first time install. NOT during an uninstall. And NOT during a repair or change.
Here's an example of the command line that I use to execute the minor upgrade. msiexec /i "C:\TestAPP.msi" REINSTALL=ALL REINSTALLMODE=vomus /l*v "C:\Upgrade.log"
Is there a way for me to condition my CA to work only during a minor upgrade ?
By definition, a Minor Upgrade is defined by the value of the REINSTALLMODE property. Specifically, the 'v' parameter that re-caches the MSI on the system. So in theory, something like:
REINSTALLMODE><"v"
Would singularly define this. But this wouldn't work in a Minor Upgrade Patch, since that relies on PATCH being set instead of re-caching an MSI package via "v". So, something like this should work a bit better:
((REINSTALLMODE><"v" OR PATCH) AND NOT REMOVE~="ALL") AND Installed
Or, if you are expecting users to only run a Minor Upgrade via the InstallShield Setup.exe file, you can just as easily rely on:
IS_MINOR_UPGRADE
(Which we set on the commandline during a Minor Upgrade with our Bootstrapper)
