I need to run a custom action only during Repair. But I didn't find a valid condition to do so. If I specify a custom action with below condition, it runs in Modify mode as well as in Repair mode.
Installed AND Not REMOVE
I am using InstallShield 2012 spring.
回答1:
Check the REINSTALL property. Conditional statement on your custom action should look like REINSTALL<>""
回答2:
For future reference check these cheat sheets:
- Installshield condition cheat sheet.
- How to add a WiX custom action that happens only on uninstall (via MSI)?
I have not had the time to go through all these conditions and test them, but the latter table looks reasonable at face value. However:
I believe REMOVE can sometimes be set during installation for example (and change) - it is very complicated to deal with all permutations of possibilities since MSI's command line interface and property configuration is so flexible.
The Installshield cheat sheet I have never actively used or checked. Please check their suggestions for repair - there are different ones depending on how the repair is invoked.
Please remember to also check self-repair - just delete the main application EXE and trigger self-repair by then invoking the application's advertised shortcut (if any). It has been years since I checked, but self-repair may only run actions between InstallInitialize and InstallFinalize.

REINSTALL="" will be evaluated to True during the install and uninstall phases so the exact condition is (Installed and NOT REMOVE) AND (REINSTALL="") because (Installed and NOT REMOVE) is True during Modify and repair operations but during repair REINSTALL property will be set to blank
