difference between xp pro & home with parallel port

[gotnoname]

I have a program what works with a dongle in stead of a serial number

now i have read that i need xp pro or win2k to use the program but i have xp home and the program does not "see" the dongle

i can install xp pro
but i wood like to know why

what is the difference between xp home and pro when dealing with the parallel port

and can i fool the program in thinking that its on a xp pro machine (with a .dll or something)

thanks in advance colin

What does a dongle have to do with the parallel port?

To answer your question...the only differences between XP Pro and XP Home are network differences. I do not see as how this should affect your program.

the dongle connects to the parralel port with xp pro its works fine ,
with xp home the dongle is not recognized

if the difference is only network why does my program not work

the manufactuer of the program specifies that I need xp pro

It's localized automatically. I just saw the webpage in English. Your picture is at an odd angle, so it's hard to see what it might be.

All I can figure is that is has some Access Control feature that lets the dongle lock the port or something
