Installed Windows 8 with Boot Camp 4 now can't upgrade to 5?

Im getting the exact same message when I try to run the installer exe to update to the new Bootcamp v5.0.5033. I've tried to Change / Repair "Bootcamp Services" from Add remove programs which results in the same message on the installer window, after closing the installer window, it says "Fatal error during installation" in another message box.

I will find out where the installer logs are being created and post an update on what i find in them when I have some more time to waste.

I was also having this issue. What resolved it for me was checking in the device manager to see what drivers the system had installed. I had previously installed AirDisplay, a VNC client, which had apparently installed its own display drivers in addition to the ones Apple had put in under BootCamp 4. I went to add/remove programs, and deleted all of the software for AirDisplay, which also deleted these drivers, and then I was able to run the installer. Hope that helps you narrow it down!

Thank you so much, that worked for me!

I removed the Real VNC Mirror driver and the Bootcamp Installer was able to start installing the drivers. I must note that during the installation of the Intel Display drivers, my screen went black and the cursor became partially responsive to touchpad input - It was able to move for about two seconds and freeze for another 2. It did this repeatedly until after 3 minutes i decided to hard reset the machine. Booted into Win 8 Pro as it normally did, I restarted the Bootcamp installer and chose the "Repair" option - everything installed successfully and ended with a controlled restart.

Im not sure what the latter issue was, but it may have something to do with the re-initialization of the monitor.

FYI: I'm using a 13" rMBP (2012)

I dont know how to flag that this relpy helped me.

Same issue here. I removed AirParrot, RealVNC and LogMeIn and the installer ran.

Thanks so much for this thread! I was having the exact same issue.

Of the mentioned programs, I only had LogMeIn installed. Uninstalling it finally let me install BC5. I then re-installed LogMeIn.

Thank you so much! This directed me to look to see what else was showing under Display Adapters in Device Manager. I found "ShoreTel Desktop Sharing Accelerator" which is part of our VoIP system. After removing this software and deleting the adapter, Boot Camp installed perfectly. Thanks again.

None of the solutions above worked for me. I solved the problem by using Microsoft's Program Install and Uninstall troubleshooter to uninstall version 4 of the program "Boot Camp Services". Once version 4 was removed I was then able to successfully run the Bootcamp 5 setup.exe program.

Similar to the experience of other people, I could not remove version 4 of Boot Camp Services from the list of programs in the Control Panel simply by clicking on the "Uninstall" option because each time I tried to uninstall it I received the following error message: "Boot Camp requires that your system is running Windows 7". The only way that I was able to uninstall version 4 of Boot Camp Services was to use Microsoft's troubleshooter.

Thank you so much - I uninstalled Logmein and BC5 worked first time

This worked for me, thanks.
