Hi, 
So I still didn't figure this out...
I did what I described, created an immediate CA which sets the value of a property I defined, to the console session's local app data path.But at the log (running the msi with L*V), it seems this custom action is executed only at the second sequence, and the installer still 'thinks' the property's value is the default one I configured at the WXS file, and the value I set using the CA doesn't affect anything.



I was then advised to create a CA which modifies the DB by inserting temporary records to the DB, but from what I understand, this is useful mainly to create features, while what I need is to modify the value of a property in order to change the install dir path while running.




I can supply a more elaborated explanation with code samples if needed,



Anyone got a suggestion for me?
I'm really stuck here..
Thanks!

You got it right, that's the way to do it.
 
 Make sure to schedule the custom action in both UI and Execute sequences and run on first sequence only
 
 The property should be in all capital characters
