I get the message Download Failed because it needs the offline installation files.
My only machine on line is running Linux.
Is there any way to down load the files on the Linux machine and then I can copy them to the Windows 10 machine?
Thanks,
Ted
Presumably, yes. I use my MacBook to download the install files very successfully.
Get the latest Rhino 7 release file from this page:
https://www.rhino3d.com/download/rhino-for-windows/7/latest
Move file to your offline machine and click it to install.
Perhaps I don’t understand your issue: under what circumstances do you get the “Download Failed” message?
