vb3 pen computing

hi,
i'm a programmer who's using vb3 to develop my own pen/ handwriting recognition program. Everything went fine but i can't seem to run my program. It kept saying it needs windows 95 pen computing extension. Can anyone help me as to what the meaning of the error is? Do i have to reconfigure some certain file in order to make my program executable? I'm working in Windows 98 OS.
