I have three different systems that I reserved the Win-10 upgrade on - 1 Win-8.1/Pro/64-Bit, 1 Win-8.1/Pro/32-Bit, and 1 Win7/Pro/64-Bit.
All three have NSwB (current version) installed (that's supposed to be Win-10 compatible).
All three received their install images this morning.
All three failed to initiate the Win-10 install process...
The Error Detail for the failed update (on all three systems) is as follows...
When I web-searched on the C1900208 Error code I found many references - Most all of them detailing the cause as being due to the installed Security software...
Any suggestions?
Cheers!
