The SP2 x64 tcp/ip patch was introduced in the latest version 1.3.5. The versions before could use this patch only with x64 SP1, or x86 SP2. If I understood well, you can not disable this patch completely, i have the options 10, 20, 50..... and "BY DEFAULT". There is no option "DISABLE", and BY DEFAULT, i have tryed, and it doesn't change anything. With the previous version, this patch is not applycable to x64 SP2 at all, so, I used this version to nlite my windows and it's working now. Actually, i'm connected to the net, and i'm writing this message with win xp 64x SP2 nlited with v1.3.0.4. Personally, I download all the versions of nLite when they comes out, and I keep them on my hdd. So, I could send or attach the 1.3.0.4, but i thing you can download it from the download page in "previous versions".
