Hello! It's seems that there is an error with the path, you need to choose the correct path for your Windows 7 x86, inside the first window's 7Customizer: I see inside your Dism.log (7C log.txt): DISM.EXE: Executing command line: "C:\Program Files\Windows AIK\Tools\Servicing\Dism.exe" /unmount-wim /mountdir:"work\mount" /commit With correct path for x86: C:\Program Files\Windows AIK\Tools\x86\Servicing\Dism.exe And you need to use 7Customizer as Administrator. Visual English guide Thank u myselfidem, As you mentioned my Dism path is incorrect, I have corrected and works properly.
