Like many others out there, I am trying to use a second computer to create a slipstreamed XP install disk. The computer I am running nlite from is a new laptop with Vista 32bit home. My XP CD is a purchased CD and is the SP1 version and I have slipstreamed time and again to add SP2 and post SP2 updates. I have even in the past slipstream SP3 RC on the disk and had a successful install, but all of these previous attempts were done using nlite and running on the XP machine I was updating. So there is no question my key is valid. I have run nlite from Vista in the Win XP SP2 compatibility mode as well. The end result is that I am told my CD key is not valid with is not true. My nlite install begins with importing the XP cd using nlite. Slipstreaming SP3 on the disk. Closing nlite and using the WMP11 slipstream too to put media player 11 in the install. Restart nlite and put several update packs and Addons including IE7 and others from RyanVM website. I add my user account info and make some basic tweaks for how things look, but do not remove or disable any components. I also add in the drivers for Raid, IDE, motherboard, printer, etc. I write all this out to an ISO using nlite, transfer the ISO to my desktop and run VMWare virtual machine to try it out using the iso as the boot CD rom. Four attempts have been made, no success yet. Originally I just ran nlite and did not use the XP SP2 compatibility mode. I tried this twice before seeing that I should do this. Then I ran it in that mode, no success. I then put the WMP11 slipstreamer in the XP SP2 compatibilty mode as well and still nothing. Some people have updated to SP2 first then SP3. OThers say not to do that. How do you make this work because the searches I have done have not provided the answer or information I need.
