Pentium III 450 processor, 360mb ram, 16x cd - old Dell computer with about 1.7gb space on hard drive. Incidentally, I have 2 hard drives, the C is 9gb with about 1.7gb space and the D is 6gb with about 4gb space, so due to more space, I originally loaded the Connect software to the D drive in a folder I named Connect Player but it would not then accept the update from Sony website. I uninstalled and reinstalled to the default they give you (C:\program files\sony\connect player - I think) and the update downloaded first time to that.
