Hi all,
I can really use your help

I've put some support files in my ism project, which I want only for installation time.

I've created a DTF C# custom action(Wix) that execute them from SUPPORTDIR
my custom Action is immidiate and is sequenced after CostFinalize

When I do the following:

string supportDir = session["SUPPORTDIR"]
supportDir is EMPTY

WHY??!!

Thanks,
Lior
