UAC (User Access Control) is a very frustrating security enhancement for Vista (and above) that execute applications using standard user rights even if you login as administrator.

Since Adobe Flash publish it's projector without administrator rights in it's manifest, it won't be able to launch installers that require administrator rights.

Amending the manifest of the flash projector to request for administrator rights execution level is a good workaround. Unfortunately and the funny thing is, some installers that do not need administrator rights to execute may fail to run or even hang up when launched with administrator rights from the flash projector!

If a flash projector has 2 installers to launch whereby one require administrator rights and the other don't, how can we resolve the problem?

Administrator rights is easily passed on to the installer using elevated mode in vista. But is it possible to UN-elevated a installer (run without administrator rights) launched from flash with administrator rights? Is there any alterative apart from using the non-UAC compatible fscommand actionscript?

Since Adobe Flash is not UAC compatible. It can no longer be used as interface to launch installer for Windows Vista and Windows 7, isn't it?
