Have you included the NI-VISA additional installer? It might exist on your XP machine, but not on the Win 7 machine.

Thanks for the reply ,

On my XP machine i installed only labview 8.5 and did the development and made a installer but it didnt work for the said operating system .My question is whether i need any addtional NI visa installer that i should take care while making installer, and how to find it out.

Sorry for confusion ,

My question is what changes i need to do in code or while making the installer to make the existing program work with other Windows operating system

You need to make sure the machine have the corresponding NI-VISA installed. Check in the NI software pages for the right version.

Also make sure that the com port's can be selected when you first start the application. Eg. if you refer to VISA "COM1" on the XP machine It might be "COM2" on the Win7 machine.
