gack somehow my reply was deleted oh well here it is again. isn't there a file in windows that handles all the assocations? and isn't there a way to add a line to a text file. now i have no idea the file name or how to program it to do that but that would be my guess. another option is the registry. i bet you could do it from there. just have it modify the reg. maybe by making a reg file to be added durring the "install" run it once and your done.
