ASP.NET and IIS Registration

I am trying to register ASP.NET 1.1 with IIS. I was told to open a
command window and run the following command to accomplish this: C:
\WINDOWS\Microsoft.NET\Framework\v1.1.4322 \aspnet_regiis -i

When I run this command I am told by the operating system that I need
administrator rights; since I am in the command window I can not right
click on the command to specify that I want to run as an
administrator.

Any suggestions? Thank you in advance.
