How to configure CA to only run during install, not during uninstall

[Dean_H]

I have an InstallScript MSI Project that contains a custom action that executes an exe after all of the files are installed for the selected feature. I only want the CA to run during an installation, not during an uninstall, how do I configure the settings iwithin the Custom Action. I have attached a bitmap of the CA. I know that the Execution needs to be changed, but not sure how to get exactly what I want

If I use the conditions "(Not Installed) AND (UILevel=5)", if an update is triggered, will this Custom Action run? I need this CA to run for New Install and Updates, but not during an Uninstall

If its JUST the Uninstall where you do not want your CA to run, you can use the condition:

NOT REMOVE

[RobertDickau]

It partly depends on what you want to do with maintenance mode, minor upgrades vs. major upgrades, etc. Ignoring major upgrades, perhaps something like REMOVE<>"ALL" to detect anything but uninstallation (but allowing maintenance mode with partial uninstallation, for example)? With major upgrades there's UPGRADINGPRODUCTCODE, but that's another story.

Thanks for the suggestion Happy Days. The condition NOT REMOVE did the trick!
