The Dimension 9100 is NOT listed on Dell's windows 7 compatibility list, however I see many posts from people who seem to have gotten it working on other non-compatible machines.

Before I open my copy of Win 7, I would like to know if I will be able to run it.

What scares me is that no matter what I do, I can not get the Windows 7 Upgrade advisor to run.  It starts up and complains about an unexpected error.

Can Windows 7 run on a Dimension 9100?
