Problem with COM port opening

I made an application using COM port to dialog with a microcontroleur and i have some troubles with the opening of the port. i developed it under window XP pro and labview 6.1 and i have no problem when i launch my application on an XP PC having labview installed or on a window 98 PC without labview (just the runtime engine). But when i launch it on an XP pc with only the runtime engine, it seems to launch correctly but in fact, there is a problem with the COM port opening. The menu allowing to chose the port number is inactive and has no effect, like if the software wouldn't recognize the material port on the PC. And consequently, nothing happens when the dialog should start.
Thank tou for your precious help

Is the VISA run-time engine installed? I don't understand why it would work on the win98 machine unless you have an older installation of it there.
