Solution for Bootcamp 6 error on Windows 10

I've had the same problem as many of you when trying to install Bootcamp 6 on my Windows 10 machine. The error about "not valid boot camp service" and wrong "bootcamp.msi" and "The installed product does not match the installation source(s)" kept popping up.


Here's what I did to fix it:


  • Create a restore point (just in case)
  • Make sure you downloaded BootCamp 6 via "Apple Software Update" (will also work if Apple releases the files directly for download)
  • Navigate to C:\Users\{yourUsername}\AppData\Local\Apple\Apple Software Update\ (you might need to turn on "Show hidden files" in Explorer if you can't see it), there you'll see a file called AppleBcUpdate.exe. Either open WinRar or rename that file to "AppleBcUpdate.exe.zip" (you might need to turn on "Show file extensions in Explorer) and double click it. Extract the two folders in there to the root of D:\ or C:\ (doesn't really matter).
  • Click the start button and type in "regedit". Right click -> Run as administrator
  • Navigate to HKEY_CLASSES_ROOT\Installer\Products and find the folder "A2C2B2AF14AEA5943980062716525D26". Rename that folder to something like "_A2C2B2AF14AEA5943980062716525D26" or whatever. You can also export it (as a backup) and then just delete it.
  • Close regedit.
  • Click the start button and type in "cmd". Right click -> Run as administrator
  • Type in "D:" (if you extract BootCamp to D:\). Then "cd BootCamp\Drivers\Apple". Now type in "BootCamp.msi" and hit enter.
  • The installer should now run through fine.
  • Restart your computer, even if you're not prompted to do so.


This is what worked for me. I have now a successful BootCamp 6 installation on Windows 10:

Thank you for posting this alxkum (and thank you to Loner T for bringing it to my attention). I cannot imagine how you figured this out!


I was having a devil of a time with this issue and wrote about it in another forum post here.


Initially there was no AppleBcUpdate.exe in the path you specified, so I ran Apple Software Update and let it begin installing the Bootcamp update. After the downloading phase finished and verifying began I stopped the installation. Now AppleBcUpdate.exe was present. The rest worked as you outlined in your post, including the Windows Installer failure message.

But that did not prevent the installation from continuing to run. After rebooting my Bluetooth mouse works (that was the only obvious problem after upgrading to W10) so I assume this confirms the BC update's success.


I'm curious is the registry edit needs to be undone for future installations to work. I did it just in case.


Thank you again!

Leave it as is. If you run into any future Windows Update issues, we can address it then. If you dislike the idea, back up the registry, create a Windows System Restore point, and then delete the specific entry and values.


If you have already removed it, there is no need to put it back.

Thank you for the follow-up Loner T. What prompted me to think that the registry edited should be reversed was this comment by eoste in earlier in this thread:

This method solves the Bootcamp 6 driver install, but will make Office 365 install impossible, if you don't rename that HKEY_CLASSES_ROOT\Installer\Products and find the folder "A2C2B2AF14AEA5943980062716525D26 as it was.


Since the key refers explicitly to Bootcamp I cannot see how it would effect installations of other software, but then "what do I know?!". Given your comment I'll reverse my reversal and put the _ back in.
