Tsertse Posted April 25, 2014 Report Share Posted April 25, 2014 Hello, I tried to install new nvidia driver for my 9600M GT graphic card. I use a Macbook pro 17' 2009, with bootcamp and windows 8.1 x64. Device Key: Enum\PCI\VEN_10DE&DEV_0647&SUBSYS_00B0106B&REV_A1 So, I downloaded the 335.23_win8X64 driver from your site and I used the modified INF. My graphic card used the driver (8.17.12.6141 from 19/01/2011), I uninstall it with the device manager, after reboot, I install the 335.23 driver with de device manager and during the installation I receive this error (The hash of the file is missing from the specified catalog file. The file is probably damaged or tampered with.) And If I try to install with the setup.exe from the nvidia folder, I passed the compatibility test, choose express or custom (new install and only driver), I always receive a failure error during the instalation. Thank you !!! Tsertse Quote Link to comment Share on other sites More sharing options...
Tsertse Posted April 25, 2014 Author Report Share Posted April 25, 2014 I resolve the error and I correctly install the new driver. The very simple solution : Press F7 during Windows 8/8.1 startup to allow the installation of modded drivers. By default, Windows 8/8.1 doesn’t allow unsigned drivers to install. Can you write this in your tuto's if it's not done, thanks you :-) Quote Link to comment Share on other sites More sharing options...
