I've merged all your topics together into this one. The next step for me is to try it with your exe files and switches. P.S. Thanks for uploading them, much appreciated. Worked fine for me. Are you installing it from USB or DVD? EDIT: Hmm, i think it only the first one installed. The rest displayed an error and made RunOnce close itself. EDIT: I believe the first one try to make the entire thing restart. You need to add /norestart after the .NET 4 ones i think.
