Does it come with anti-virus software pre-installed? Certain anti-virus softwares will give problems. Mcaffee is one of them as I've found out. I'm not sure for other anti-virus softwares, but disabling them will help through the installation process...
I have to agree that it runs ok with winxp... but I've had a nasty experience installing it until I realised that some other softwares may cause conflict. So check it...
I don't know why but my 0/2/C lic does not work (yes, it's a C lic) . Could someone tell me what difficulty you have had and what you did to overcome it please.
I'm about to give up with 2/0/0/2"C", (have 2/0/0/2 running fine).
