Uninstaller + UAC plugin + Vista = confusion

[Anders]

If you write the uninstall entry in HKCU it does not elevate, when you write to HKLM, it is a all-users type install and you should probably be prepared to handle any user uninstalling it.

If you add two dwords to your uninstall entry in HKLM:
NoElevateOnModify=1
NoRemove=1

you sort of get the desired effect, only problem is that the UI now calls it change instead of uninstall

Unless MS provides another dword for uninstall to disable elevation, there is probably nothing you can do (too late for RTM)

The UAC plugin was mostly designed for install use, not the uninstaller (Solve the run checkbox problem on the finish page)
