I have a plug-in for Office (word, excel and powerpoint). It works fine with Office 2003 and 2007. Plug-in does not support Office 2000 (or any versions other than 2003 or 2007) .
I get a problem on a system which has Office 2000 and Office 2003 installed with my plug-in. As the registry entries for Office applications is common for all the versions of Office at- "Software/Microsoft Office/Office/Word/Addins". So, Word 2000 tries to load my add-in too. How can I avoid Office 2000 to load my add-in during startup and allow Office 2003 and Office 2007 to load the add-in.
