I have developed a simple managed com add-in in vb.net for MS Word 2003 which displays two message boxes in OnConnection and OnStartupComplete events. I did make the setup and installed it which is running fine. Now i deployed the same setup in another machine which is having windows 2000 SP4/.Net framework 2.0/word 2003/IE5 only installed on it. It does not displaying any message boxes. I did check the registry keys and i found that when ever i open the word application the addin "LoadBehavior" parameter becomes 2 instead of 3. Can someone please throw a light why this addin loadbehavior becomes 2 ? Cheers Praveen
