Firmware Install Issues
I’m not sure if I have the same root cause of the problem as others in this thread, but I had the exact issue as the OP and solved mine by temporarily pausing my antivirus software. They are apparently on a hair trigger these days. I had a similar problem recently with a device driver installation and found that the AV software was deleting files as soon as they were unzipped without even giving any kind of message about that. YMMV.
