Question: Cannot update nvidia drivers after installing bootcamp drivers

Hi everyone,

I'm sorry to start again a topic that in my view has been treated many times, in many forums but HAS NOT been solved so far...I looked over many forums over the week end and tried a number of "tricks"

I'm running Windows 7 Pro Sp1 32bits on a MacbookPro 17 - intel core duo with two graphic cards but for better performance running the Nvidia GeForce 9600m GT

I have installed Windows 7 this week and then Bootcamp 4.0 - thus i have now Bootcamp drivers, ie 261.41

I have installed Battlefield 3 which asked me to update drivers to at least 285.27

I downloaded them from Nvidia site 285.27 AND 285.38 (m version - notebook) but when i start the indatllation i get the message "hardware not comptatible"

So far i have tried 1) to install non-beta older versions but higher than 261.41 (which is by the way only available on bootcamp) - it does not work 2) uninstall nvidia drivers, restarting windows with VGA driver and install newest nvidia drivers - it does not work;

What i have not tried (as it was not clear on other forum): 1) replace an INF file? - i did not understand what i have to do here 2) update other drivers? mobility? ATA? - i'm not sure what people were talking about here?

SORRY MY MESSAGE IS LONG BUT I REALLY NEED YOUR HELP - and want to play battlefield 3 that i pre bought by the way... ;-)

MacBook Pro, Windows 7, Nvidia GeForce 9600m GT

According to my read of the Nvidia page referring to their LATEST driver for te GeForce 9600m GT that WILL PLAY BATTLEFIELD 3, the correct driver Version is "280.26". The driver you mentioned , 285.27, is the Latest NVidia general GeForce driver, but it is apparently Not yet fully compatible with your GeForce 9600m GT which is specifically a notebook video card used ONLY for Apple computers which have slightly different characteristics than pure MS Windows based hardware.

From the Nvidea website:

NVIDIA GeForce 280.26 WHQL Drivers Released

August 8, 2011

By Andrew Burnes

The new GeForce 280.26 WHQL drivers are now available to download. Filled with fixes, new and updated 3D Vision profiles, and a couple of new features, the drivers are an essential upgrade for those seeking the absolute best from their games. Compared to the 280.19 beta drivers released July 28th there are a few minor changes included of little note, in addition to a number of new 3D Vision profiles.

Though not mentioned in our release notes, we recommend that NVIDIA GPU users testing

Battlefield 3download these drivers to help eliminate any in-game glitches they are experiencing.

Hope this helps 🙂

OK, having the same issue and Ive tried everything. Macbook Pro, running bootcamp with a Nvidia GeForce 9600m GT, my main issue is with Portal 2, it wont let me update to 280.26 at all, getting the same hardware not compatible error. Is there anyone who can figure this out?

I make this post as I found a way to solve my issue and this could be interesting to other people:

1. Download the latest nvidia drivers (285.38) on nvidia website: http://www.nvidia.com/Download/index.aspx?

2. Launch the .exe it will unpack the package in one folder: most likely NVIDIA/DisplayDriver/285.38/WinVista_Win7/International

3. Your installation will be cancelled through "hardware not compatible" - no worries you still have the unpacked stuff.

4. Go to http://laptopvideo2go.com/drivers/win7x32/285.38/disclaimer and click on "Click here to download the modified INF file." on the bottom - this will download a file called nvwi.inf - copy it

5. Go to the unpacked folder and go to the folder named Display.Driver - paste the nvwi.inf - it will replace the actual one

6. On the root folder (International) click on setup and you will be allowed to install the drivers - note that i have accepted during installation two times that it install drivers not "allowed by windows" (different topic)

Hope this helps.

Actually, it does work. I just tried it myself so I can play BF3.

The problem is though that the link budfox75001 posted is for the 32 bits ini file, in my case (and I guess yours as well) you will need the 64 bits file.

Try this link:


I used it on the 285.62 and it worked like a cham. Its a b*tch though that one needs to do that in order to get stuff to work.

Thanks Budfox!

Hey Budfox,

Im having a problem replacing the inf file. I have tried to drag it in and it just sits below the original. I have tried removing the original and leaving the new modified inf. I have even tried replacing the text itself with the original with new modified. Ill either get the original "hardware not compatible" or "files are missing". Can you help me figure out what im doing wrong? I made sure to have the right 64 bit version.
