Is anyone else able to run Graham Wideman's demo Visio controller
http://www.grahamwideman.com/gw/tech/Visio/delphi/index.htm (http://www.grahamwideman.com/gw/tech/Visio/delphi/index.htm)
(download the zip file and run the exe file, you don't need Delphi). I can run this file on Visio 2000/2003 and 2007, but it fails with an exception on Visio 2010 (Exception EOleSysError in module GWVisio_Demo_01.exe at 000480C9).
Right-click the .exe and choose "run as administrator"
On my Win7/32 machine, Graham's GWVisio_Demo_01.exe didn't work for Visio 2010 nor Visio 2007 until I ran it as admin.
You are so right! Thanks. The good news is that the error I was seeing has helped me find a start up problem in one of my own addons. 8)
