OK, I figured my particular case out.

The condition you want to use is simply "NOT Installed".

Example:

<Custom Action="MyCustomAction" Before="ProcessComponents">NOT 
Installed</Custom>

In this example, the MyCustomAction action will be run during the installation 
sequence, but will not be run during the uinstall sequence.

Subject: [WiX-users] How To Run Custom Action During Install But Not During 
Uninstall

Is there a good FAQ anywhere? It is so frustrating trying to figure out how to 
do things that zillions of others must be doing all the time...

In my case, I just want to run a custom action at install time. I have the 
custom action running just fine at install time now, but it also gets run when 
I uninstall the application.

How can I stop it from running during the uninstall?

Thanks in advance!

Brad
