I am trying to make a silent install and am having some problems:

OnCheckSilentInstall is not getting called, which doesn't cause OnMsiSilentInstall to get called.

I tried to see if I could insert the action, but it wasn't availble for any of the types in the dropdown list.

I've added a handler for the latter to my script, but it never gets called. No matter I specify "qn" or "q".

This is an InstallScript MSI project, in the new style UI (WI 4.5 required). The system I am testing on is on WI 5.0.

Can someone help explain what is going on?
