Thank you for offering to help! Yes, I was able to download to the Win10 laptop, at least it seems so in my non-technical perspective.
Very curious, where does one find Win7 compatibility mode on the Win10 laptop?
Apologies, your suggestion of 'put your license and data files on a 3rd party cloud hosting running on Win 7' is over my head! I wouldn't know how to present that to the org I work for!
