We have a COM addin that is registered and the registry setting is set to load it at startup( setting = 3). It doesn't get loaded and it doesn't appear in the COM Addin's list. When we browse to it to load it, we can select it but it still doesn't appear in the list. I have seen this behavior before on another COM addin, many months ago then it went away, i.e. it would load correctly, but this new COM addin is never loading yet it use to. Any ideas
