Issue with Visual Studio 2008 Web Setup Project

Hi

i have a web project in VS 2003, which has an installer class added. the web setup project has a custom action and the code in the installer class gets executed during install. if a domain admin is running the msi package then the code in the installer class gets executed under the idenity of domain admin. this is required because certain steps in the installer class require admin privs to be performed.
i have since moved to VS 2008...and have one major issue. the code in the installer class now always gets executed under the windows idenity of “NT Authority\System”, and not domain admin, even though that's who i am logged in as.

thanks in advance

john

further info that I found is that code in an installer class runs under the logged in user for the following setup projects:

VS 2003 Setup Project
VS 2003 Web Setup Project
VS 2008 Setup Project

the only setup where it runs under NT Authority\System is VS 2008 Web Setup Project
