I made a simple program for my mom and she installed it no problem and ran it with no problems. now I gave it to my sister and she ran it with no problems. both on win98se. but I gave it to my boss and she ran it on the work computer (win2000) and it runs ok. but when she click on a menu item to open another form she gets an error. the error states

Run-time error '-2147220999 (800401f9)':
Method '~' of object '~' failed.

I included most things in the package when I ran package and development on my vb6. all that form is is a listview that opens a database. it uses jet so I included those dlls and ocx or what ever it takes. so she took it home to her computer (win98se) and installed it and ran it and click on the same menu item and gets another error different from win2k. it reads as follows

class doesn't support automation or expected interface. also it was a run-time error. don't know the numbers.

does anybody have an idea or a source that shows what each error code it or how to fix it.

TIA
