I have a very old ArcMap 9.2 with VB6 add-in. Recently, I have added one more button to the add-in. Then I have used Add-in -> ESRI Compile to generate the dll and the registry. The new button runs fine on the development machine. But when I deploys the dll to other machines (import the registry and then copy the dll to C:\Program Files), the button is not shown in ArcMap. When I try to import dll from Component Category Manaager, "No registered file can be found error" is shown.
As the version is too old, I cannot find any related resources. Anyone can give me a hand?
