I installed Geodatabase Diagrammer Add-Inn. First I got a bunch of errors, I fixed them by oen Visio then open/close from Visio each file. Then I double click on the file itself. Now I dont get the errors but it keeps spinning and spinning. I even let it run overnight and the next morning is still spinning. Need help!!! I have ArcGIS Advanced 10.1, Visio 2007 SP1 and OS=Windows 7 64bit.
