I tried the reverse integration method to integrate the SP2 in Vista Source. I followed all the steps and I managed to integrate SP1+SP2+IE8 in Vista Source and Home Premium Edition. I replaced the new INSTALL.WIM, burned the image and all are working fine. Then I tried to go one step further and add anothe image in INSTALL.WIM. I installed Vista Ultimate in audit mode, installed SP1+SP2+IE8 and I used the imagex with "/append" switch to append my image. I replaced the new INSTALL.WIM and burned the image. Now when I try to start the install with the new media when I go to the step that I have to type my product key and I leave it black and select "next", I got a message that says "that setup cannot display the images" and quits. Can anyone explain this?
