For UAC, deferred is the right thing to do, and running without impersonation is also the right answer. Unless you have arranged to run the entire MSI install elevated, running impersonated as Administrator really means "...but with a limited user token", and immediate custom actions won't be elevated. I can't tell from your post whether you tried one of these then the other, or both together, but you should be trying deferred AND not impersonated.

I was testing the issue I'm having with permissions on service installs on my vista system and i came across another issue. When I attempt to run a command using QtExec I get an access denied error. I've tried to make it a deferred custom action as this has been recommended on some sites but with no joy. I've tried to stop it impersonating local user too, even though the local user is admin. so... this: <Property Id="QtExecCmdLine" Value=""eventcreate" /T INFORMATION /SO ISRM_S /ID 1 /D "INSTALLING SERVICE EVENT SOURCE" /L APPLICATION"/> <CustomAction Id="QtExec" BinaryKey="wixca" DllEntry="CAQuietExec" Execute="immediate" Return="check" Impersonate="no"/> <Binary Id="wixca" src="wixca.dll"/> <InstallExecuteSequence> <Custom Action="QtExec" After="InstallServices"/> </InstallExecuteSequence> produces this: MSI (s) (58:00) [07:45:30:284]: Hello, I'm your 32bit Impersonated custom action server. MSI (s) (58!50) [07:45:30:331]: PROPERTY CHANGE: Deleting QtExecCmdLine property. Its current value is '"eventcreate" /T INFORMATION /SO ISRM_S /ID 1 /D "INSTALLING SERVICE EVENT SOURCE" /L APPLICATION'. CAQuietExec: ERROR: Access is denied. CAQuietExec: CAQuietExec: Error 0x80070001: Command line returned an error. any ideas? Sorry for the constant questions guys, I just don't know where else to turn if google fails me. It's not like there is a good book on WIX out there that i know of.
