Windows 10 Upgrade Error 800704DB
Trying to Upgrade to Windows 10 Pro (from Windows 8.1 Pro), getting error message 800704DB. I get past the initial 'agreement' and it then goes through various processes and asks what to keep. Then the install begins and opens into full screen. At around 23-25% it stops with the error message as posted above. I have tried every which way, windows update, from ISO DVD, and from extracted files on different internal hard drive, and USB key.
I got onto MS Tech Support, who after some time decided to remotely help me with the install. The support guy had the exact same problems and did not know what to do. I was eventually passed on to a higher support person.
He decided that as I had a custom built PC, this was the problem. He told me the only option was to upgrade but without keeping anything, and left me to it! Well guess what? If failed in exactly the same place AGAIN.
I was no longer with Tech Support, so I got back onto them. The only suggestion they have for me is to do a clean install of Windows 10, but I have to purchase a Windows 10 Key for $135.00!!!!!!!
So much for a free upgrade.
I have installed the preview and current ISO into a virtual machine without any problem, so it should work. Maybe it is some software or hardware stopping the upgrade.
Anyone else heard of this problem?
