How tell if INSTALLDIR is set from the Command line

[DLee65]

I am trying to figure out what property to check to see if INSTALLDIR is set on the command line so that my custom action does not overwrite the user's command line setting.

This is a basic MSI project. I am basically looking to set a condition like this on my custom action:
NOT COMMANDLINE><"INSTALLDIR"

While not exactly what you asked, this thread should give you enough to run with...

I think I can get something like this to work. Unfortunately I cannot get it to work exactly as Christopher indicates because I cannot set INSTALLDIR until the user enters a license key and the key is verified.

But I can create a property based on this and then use this property to determine if INSTALLDIR was set on the command line.

Thanks for the tip.
