[wix-users] Set property from custom action?

[Alon Dean]

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!
