I'm currently developing a C# addin for MapPoint 2004 North America using VS2003.
I have installed and run the addin on my machine (the same machine used to develop this addin) with no problem. As soon as the MapPoint is loaded, the addin command name is displayed in the Tools menu. When I try to install this addin from the MSI file on different machines, the addin fails to load the in MappPoint application. The MapPoint addin manager sees the addin, but the check box near the addin name is not checked and the addin command name is not displayed in the Tools menu, and even if I check it, it still doesn't load.

What is wrong with the addin ? Can someone help me, please ? Thanx a lot in advance !!!!
