boot camp installation hangs at realtek audio stepSearch or ask a question

Ok so I was having this issue with Windows 10 build 10565 ISO. I found an older ISO from August (looks like RTM build 10240) and Bootcamp setup works fine on this version.

Try a wired connection instead of a wireless connection. The slower the wireless connection, the more likely it will fail.

Theres some instructions on how to http://tonyandtech.blogspot.com/2016/01/boot-camp-keeps-on-freezing.html

Please see Bootcamp 6.0 driver install interrupted (it does refer back to this discussion). If access is denied, are you using an account with Admin privileges?

Is this a clean new installation? You can also remove the RealTek folder (on specific Macs) and run the setup.exe.

Wininstall is on your thumb drive with the windows boot camp support files. If it is not there, try to create another support file download in iOS.

Is there a trackpad tab in the Control Panel -> Boot Camp? You can try a SMC and NVRAM reset to reset the volume db.

There are some registry settings for scrolling that you will have to explore further. Look in

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID\VID_???\VID_???\Device Parameters

Please see http://superuser.com/questions/310681/inverting-direction-of-mouse-scroll-wheel as a reference.

You should either have a partition called OSXRESERVED or the USB Installer should have a BOOTCAMP folder. If you used Apple Software Update to get the drivers, it should be C: (search for it).

Please back up OS X, Windows and create a Windows System Restore point for future recovery.

Please see Bootcamp 6.0 driver install interrupted .

An alternative solution would be to just delete the Realtek file.

That fixed it for me.

Can you re-run setup.exe from Bootcamp folder on your USB Installer? If you did not use a USB, download BC drivers for your model from OS X BC Assistant as follows...

I can confirm this works. Incredible we still have this problem in windows 10 and El Capitan.

Also, check the detailed instructions by jmwils1, posted later.

I'm having the same issue with Windows 10. Anyone found a fix for this? I tried going into the Bootcamp installer folder and install Realtek drivers manually which succeeded, but when I launch the Bootcamp installer again, it still gets stuck when installing Realtek drivers.

Greetings; I'm grateful to jmwils1 for posting additional detail as I was able to resolve the realtek driver issue by combining replies from lincizy and jmwils1! Thank you both very much for taking the time to do document your findings! I hope to pay this forward someday to someone else in need!
