I'm running Windows 7 on a Boot Camp partition on a 2010 Mac Pro running Lion.

Every so often I'm prompted to download and install the latest update to the Boot Camp software under Windows but this doesn't ever seem to update the installed version of Boot Camp. I also get prompted to do this when in OS X.

Should I update both or one of them? And if the latter, should I do one before the other?

I found a thread related to Display Drivers in Windows that stops the 3.2 and 3.3 Updates from installing correctly.

The core point is that if there are other display drivers showing in device manager other than the default display adapter (users reported issues and resolution after removing VNC or LogMeIn Mirror display adapters).

The original discussion is here Bootcamp 3.3 fails to install


I would update them both and I don't think you need to do one before the other. I have not had any problems updating one before the other and I manage large networks of Macs.

  • I've tried doing both OSes, in different orders, with the 3.3 updater, but I'm still stuck at 3.2 :-(

Boot Camp essentially consists of 2 functions.

One is the capability to provide for dual booting, doing the legwork required to get Windows to boot from the Mac EFI BIOS for want of a better description, performing the relevant partitioning etc (note you can do this yourself). This portion is really the Boot Camp Assistant part, namely an executable Mac program.

The other part of a collection of drivers for Windows systems that allows your Windows install, once completed, to gain access to all the functions your hardware has to offer, so making sure your Facetime camera works, providing a sensible (well, sort of sensible it can be argued) keyboard mapping and trackpad driver, and various other bits and bobs. For example a recent update in this area allowed bootcamp installations to not fall over and die at the sight of a Filevault 2 protexted Mac filesystem...

When an update to bootcamp is available, it could be an update to the assistant program that you won't really need once you have already installed Windows, or updates to the driver packages etc. Depending on what type of update, this may or may not increase the version number of the BC Assistant. Some are large, some are small. One Bootcamp assistant update did nothing except remove the Beta tag that it had when Tiger first introduced bootcamp. Others are very large, such as the one that provided Windows 7 drivers for all your hardware. Some are small but very important, such as the FileVault update.

You may as well update whenever you see one available. if you are worried, give it a week and see if a poo storm erupts on the internet after release.

  • I'm not sure you've actually read my question? I would love to 'update whenever I see one available', but I can't !

    Hi @5arx, Sure I read it, I can't see where it says you cannot do it, just questions asking if you should. Maybe an edit for clarity would help.
