First, I would like to thank you for your tools. Second, I think the only thing missing for got an entire "replacement for vlite" application, it's an iso maker build in 7customizer ; so I would like to submit an idea : why don't you add a path line under "Dism" and "ImageX" wich ask for the path of "oscdimg" ? I use this line and it works fine for me : oscdimg -u2 -m -h -b"D:\System\TOOLS\WIN7_UPD\boot\etfsboot.com" "D:\System\TOOLS\WIN7_UPD" "D:\WIN7_UPD.iso" -lWIN7_IMAC24 (Information for user of certain MacUser : if you make your "iso" with this standard command line it wiil fix the EFI boot problem). Thank you very much for reading me. jL (France)
