Programmatic way to run a program as administrator in Windows 7

Thanks dglienna, but my requirement is different. i just want to do the following steps in a double click of dll.

1. run command prompt (cmd.exe) with 'run as administrator' option
2. register the dll with regsvr32 (regsvr32 [dll path])

if the user is not an administrator, he should be prompt to enter administrator password and username. After entering the same, dll should get registered with admin privileges.

You can't do that in Windows 7, as the Trusted Installer Service has to be invoked to register files

Is there any way to do this?
