I have also had SP1,2, & 3 without a glitch. This may be a mute point, but are you set as the Admin on the XP box ?? Not sure if this will help but AFAIK you have to be set as Admin. Other than that...??? SP1 may be the alternative.
You are using an older version of Pro. You might back up that installer and try a Later Version of Basic, just to see if that may be some of the Problem. 4.18.8 is the latest stable version out, I believe. I don't use LW much anymore so I'm a little out of touch. |
