I assume that you have done the following:
* You installed NodeXL using the Setup program you obtained from the Downloads tab on the CodePlex Web site, and the Setup program ran successfully.
* You started NodeXL from the Windows Start menu by clicking "All Programs" (Windows 7 or Vista) or "Programs" (Windows XP), then "Microsoft NodeXL," then "Excel Template."
If this is the case, then please tell me the following:
1. Is there a "NodeXL" tab in the Excel ribbon? It should be to the right of the "View" tab.
2. If so, what happens when you click NodeXL, Graph, Show Graph in the Excel ribbon?
