Hello all-- I was wondering if anyone has run into this issue... I have a previous vLite version of Windows Vista that I have been using for some time now (that does not have SP1 included). I tried to slipstream SP1 using this DVD, rather than the original. While the process goes as planned, when I try to open up the setup file it gives me the message: "...setup.exe is not a valid Win32 application" and will not let me continue. I am sure that the SP1 standalone executable I have is for the 32-bit version of Vista, and my DVD burner is brand new (purchased not more than three days ago). If ANYONE has any suggestions, they would be greatly appreciated. Thanks in advance!
