I just installed Windows 10 on a late 2015 iMac. Because I had a free upgrade from Windows 8 to Windows 10. The only way to install Windows 10 and activate it was to start with Windows 8 and bootcamp assistant, they upgrade to windows 8.1 and then to Windows 10. Everything looks good bit I do have a yellow triangle next to the bluetooth driver. I there a way to download the windows 10 bootcamp drivers and rerun the install from windows?
 
Yes. Try running Apple Software Update from within Windows and report back with your Mac's model and year (e.g. Mid-2012 MacBook Pro 13").
I tried the apple software update and it just gave me options for iCloud for windows and iTunes. I have a iMac late 2015 27" w/i5 3.3 Ghz. I can recall in other versions of bootcamp downloading just the drivers from apples site, but can find the files for the current bootcamp.

Try getting a blank USB drive and firing up Boot Camp Assistant in OS X and only choosing the option for downloading the latest software. Then install it in Windows off the USB drive.

Interesting I tried to launch bootcamp assistant and got this message...
 
How is your startup disk configured?
It was just OS X and windows. But I think I found the problem. To install os x I needed to install windows 8 then upgrade to 8.1 then to windows 10. I remember the 8.1 update causes the partition table to become corrupted. I checked the disk in disk utilities and found two small partitions which I believe is causing my problems. everything is backed up so now I reformatting the disk and will restore windows via incline and see what happens.

Sounds like a good plan and remember to download the updated Boot Camp 6.x software using the method I stated through Boot Camp Assistant.

This is no longer true as of a few weeks ago

Now, Windows 10 will recognize your W7 thru W8 keys automatically

So, since you're redoing it, I would do a clean install of OSX then do a clean install straight to W10

When I try to install it on my Windows 10 partition, I'm getting the below series of errors. After the first message it gives me the second, advising me to find the BootCamp.msi file somewhere but it's nowhere to be found on my computer (per the third error). This has been happening since Boot Camp 6 became available, I simply can't update. Has anyone else seen this happen when trying to install?
