I can confirm the problem. I had it on 2 different devices running Eset Endpoint AV 6.2 and 6.4.
I could only upgrade to 1607 after uninstalling Eset before upgrading Windows 10.
I also tried it with the newest ISO, but this showed an error regarding the driver installation (probably the same you were seeing in your log).
I think I will open a case as this can't be a normal operation for an Enterprise product.
Imagine uninstalling Eset on 100 PCs, leaving them half-protected by Windows Defender until WSUS got everyone upgraded, and then having to reinstall Eset on all of them.
Sound like a week of unnessesary "fun" for the admin (me) every 6 months, when MS puts out a feature upgrade!
