In vb4 I'm trying to have a button either setup a program(if it is not on the computer) or shell to the program if it is already there. I would like to use an If....Else but I can't figure out how to use the fileexists wording.

Oh, you are using vb4. Try and see if getattr exists. If it does just replace vbFileAttribute with the return type of getattr
