Hello nanitoboy! It appens to me sometimes when I've used $OEM$ (with RunWPI.exe and cmdlines.txt) folders with WPI folders not matching - different version!! As kelsenellenelvian suggest you: download the latest WPI 8.1.0! And set inside $OEM$ the files "RunWPI.inf" and "cmdlines.txt" Maybe your Antivirus Norton Security or other Antivirus delete the file RunWPI.exe? It appens to me with NIS 2010!! Disconnect to the Internet and desactivate your Antivirus, and check if inside your $OEM$, RunWPI.exe is inside, and after you can burn your DVD! If you want to keep the old WPI version. Don't append - in my case - with WPI 8.1.0 (with RunWPI.inf)! Don't use WindowsInstaller-KB893803-v2-x86.exe, because don't work for Windows XP SP3. You can integrate successfuly WindowsXP-KB942288-v3-x86.exe Windows Installer 4.5 Redistributable - Español with nLite! Could you send as attachment your "cmdlines.txt", please? Regards Hi again myselfidem! Ok im going to integrate the new version of windows installer Now that I was thinking about what I did with nlite I remember in the components section I selected to remove "Framework option" because I was thinking to install it later. Could it be? Maybe is something that I remove in the CD with nlite. I send the cmdlines.txt With regards cmdlines.txt
