$(env.TEMP) would give you the environment variable's value on the build machine, which doesn't help at install time. So this doesn't really solve the problem of finding the environment variable's value on the user's system. It also still gives the value of the environment variable as it is set for the user, not for the system.
I'm pretty sure that to get the System's value, you need a dll custom action. But, even though you can do something, doesn't mean you should. I would highly advise against modifying the permissions on anything that is not specific to your own software. System folders fall into that category. Don't do it. The only time I would think modifying permissions of system folders would be acceptable is if you're deploying only onto machines where you are the administrator. But if you are the administrator of the machines, you've probably got other methods of determining where the system temp folder is and changing its permissions. -Ari -----Original Message----- From: Eitan Behar [mailto:ei...@baconao.net] Sent: Wednesday, February 04, 2009 10:50 AM To: General discussion for Windows Installer XML toolset.
