Thanks for the response.
I tried running those actions in the initializer but without success:
Microsoft.Deployment.WindowsInstaller.InvalidHandleException
What I've done in the end, was to initialize the property to a default value
(the same as in the wix file):
session["INSTALLLOCATION"] = string.Format("{0}\\SampleWix",
Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles)));
As long as the same person creates the wix file and the embeddedUI code, it
should be fine.
