[IronPython] Detecting IronPython Installation Directory

[Jeff Hardy]

Hi,
Thanks for the tips! To add a little bit more info, I'm working in
Powershell for various reasons, so P/Invoke is out of the question.
Using WMI is easy enough, but I'd prefer not to be mucking around
inside Windows Installer if I can help it.

Is there any reason to not include an entry (e.g.
HKLM:\SOFTWARE\Microsoft\IronPython\InstallPath) that stores the
installation path?. It's easy enough to do with WiX.

- Jeff
