and as a follow up on this:
Do all managed custom actions require elevation under Vista? I have one
defined as
<CustomAction Id="MyCA"
BinaryKey="CustomActions.dll"
DllEntry="MyExampleCA"
Execute="immediate"
Return="check"
HideTarget="no"
Impersonate="yes" />
And it does absolutely nada under vista with UAC turned on.
