We just upgraded to SW2011 SP4 from SW2010 and now Circuitworks is broken.
When I enable the CW add-in, the tab does not pop up in the feature tree. The CW menu shows, as well as the CW tab in the feature manager. But, a new tab should be created after the "ConfigurationManager" and "DisplayManager" tab. Anybody else see this?
It was a bit buggy in 2010 too. Often, you had to toggle on and off the add-in to get it to show up. But it eventually did show up.
