Opps, I didn't see "run as administrator'. Let me try that and I'll report back.

Receiving same error even running application as administrator.

We have analyzed the log file, WinToUSB does not have permissions to write the registry, this is usually caused by an anti-virus software. So please temporarily deactivate your anti-virus software or add our WinToUSB to the list of allowed applications (may be called Trusted Applications/Whitelisted applications) of your anti-virus software and try again.

It's a domain user.  I'll try to disable anti-virus.
