It appears my dilemma has been solved.  I managed to borrow a Windows laptop and I installed VMware Player on it and copied my virtual machine files to it.  When I tried to open my Windows 10 vm, it wanted to know where the Windows 7 vm was.  I pointed to it.  Apparently, when I created Windows 10, it was linked to Windows 7?

When Player started up Windows 10, the Windows 10 startup page appeared, but then it switched to the Windows 7 startup and Windows 7 started.  That didn't help and I couldn't find a way to mount another file.

I then downloaded 7-Zip and opened the file and lo and behold, there were my files.  I copied them to a local drive and they all appear to be there.  I haven't yet tried to open a sampling of them, but I feel good about it.

Thanks to all for you assistance with this issue.
