error while installation of forms and reports 6i

I am installing forms developer from forms anf reports 6i software.when i install this it gives an error a file is missing of forms builder, i ignore that and installed,but when i installed in xp os it gives an error like os-error while spawning ifsrv60 install forms60server port=9000 mode=socket batch=yes.

perhaps due to this when i debug any forms that i have made compile successfully but it does not run it gives prigram error.

i am in great trouble from last 15 days.
plz help anybody
