I am using XP now, I got this program when Windows 95 was still the newest OS. It still works up to now. I thought this will crash during the turn of the Millenium (y2K) but I am still using it. Have not tried Vista yet for this program.
If u are prompted to register put in the customer code the numbers 23077 or 17455.
Use the selection using the phone in code and don't use register via modem. Hope this helps.
