We are working on creating an installer using WIX. We have a couple of custom actions that are going to require elevation to run on Vista. Our MSI obviously elevates itself, because I get a UAC prompt and it writes keys to HKLM. Our managed DTF custom actions are apparently not running elevated. If I start the MSI from an elevated command prompt, the installation runs fine.

The only workaround I have seen suggested (link) is to use another exe with a manifest as a bootstrapper to run the MSI. This is not a good solution, as it doesn't allow the user to modify the installation by selecting "Change" from the Add/Remove programs dialog. Our install has multiple features that can be customized, so we want this functionality.

Does anybody know how to do this?

The dynamic type in C# 4.0 is a welcome addition to the language.
