I have run into this same problem when installing several different add-ins under Excel and Access. I'm running Windows XP and Office XP, and I am logged into Windows with administrator privileges. When I attempt to install a third-party add-in, it gets all the way through the Setup utility for it, to the point where it makes the registry edits, and then I get this error:

You do not have access to make the required system configuration modifications. Please rerun this installation from an administrators account.

This has happened on 3 different 3rd party add-ins from 3 different vendors.

Things I have already tried:
I have tried using Run As to run as Administrator, and it makes no difference.
I have tried it with Simple File Sharing enabled and disabled.
I have tried it with Use Welcome Screen turned both on and off.

I have no problems installing any applications on this PC. It's a normal PC in a small peer-to-peer network, and it shares its Internet connection with acouple of other PCs.

Even if you try Run As adminstrator there may be some things it won't let you do. Try logging in as the administrator and running it again. Make sure there are no permissions set on the C drive or any relevant directories (I've seen people with thewinnt directory and it's contents with permissions set for read only for Administrators!!!). Try running on another machine. If that works, start comparing the setup of both the machines. In Win XP, goto Local Security Policies in Control Panels\Admin Tools and start plowing through the securitys in there!

This was a good answer, and thanks for reminding me about checking Local Security Policies, but unfortunately no luck; all the permissions and policies are set to normal-to-liberal settings, and I had already tried to run it as "the" Administrator.
I'm going to leave this open in case someone who has had the same problem happens to read it, but thanks for your input.
