RunTime Alteration to Directory Table

Starting a new topic - this is a reply to someone already but i am not sure everyone will see it as it is old - sorry if i got that protocol wrong!
---------
Here is what i want to do: I need to install things to two places:

1. Programs are to go to [INSTALLDIR] eg c:\program files\myApps
No problem with that.

2. Some user files are to go to CommonAppData\myApps.
No problem with that either, 'myApps' is the default.

But - the user can change [INSTALLDIR] to say c:\program files\FRED\.
If they do this then the user files must go to CommonAppData\FRED.

So at runtime, i have a CA running as a DoAction on the Next button on DestinationDialog. This CA parses FRED out of INSTALLDIR by seeing what comes after c:\PRogram Files\ string, and sets a property called USERFOLDER (which is actually a Directory Table item) to CommonAppData\FRED. THis CA does seem to run AFTER CostFinalize which is where i think it is supposed to be. I use MsiSetTargetPath()

But in my final installed folder structure i do not get FRED but i get a folder called [USERFOLDER] ie the property in Directory table has not been resolved. Is that becasue i am doing things at the wrong sequence? Is there another better way, given i don't know till runtime the Property.

Here is part of my Directory Table:

Directory - (s72) - Parent -- DefaultDir
_USERFOLDER_ - CommonAppDataFolder - _USERF~1|[USERFOLDER]
USERFOLDER - CommonAppDataFolder - DEFAUL~1|Default Place

thanks
