In the latest version of Installshield (2012 spring), you can use a Powershell Custom Action. Is this any version of Powershell, or just the latest version (3.0)? How to you get and set installer (Session) properties, and, write to the log. Are there any examples of this? I could not find anything searching this forum, I see that others have asked this question previously, but have not received any replies.
The following is from Flexera support... "PowerShell is run out-of-process without access to the installer session. An in-process model, which would allow access to the installer session, is under consideration, but access to the installer session is not available at this time."
Personally, I feel that the documentation should state this, else someone might purchase or upgrade to Installshield 2012 Spring, to be able to write custom actions that access the session...and be disappointed.
