I have made sure the .exe file is on the desktop, and i have ran this code to update the BIOS: C:\users\*****\Desktop\Latitude_5X90_1.11.1.exe /p=***************** /s /r /l=C:\log.log. However, when i do so i get this error: Latitude_5X90_1.11.1.exe returned error code 10. I have done my best to make sure there aren't any syntax errors and I made sure i could manually download the update by double clicking the downloadable from the Dell website. I just can't get the command line to work. Has anyone else experienced this or know how to fix it? Any advice would be very much appreciated.
