I have created the default add-in using visual studio..when I execute
I get the addin in the addin manger but it's not displayed on the ribbon.
I'm using ST9 , SolidEdge.Community.AddIn 108.0.0 and Interop.SolidEdge 109.1.0..
Please post to the Solid Edge Developer Forum... They will be better suited to answer this question.
My guess if you are seeing it in the add-in manager but not the ribbon is that your code did not properly add it to the ribbon as it appears it is registerd.
