Some time ago Xilinx released a
special version called "ISE Design Suite v14.7 for Windows 10". When you download it you find the last updated package was made for a virtual machine on February 2020.
You need to enable all the virtualization options in the BIOS of the PC, and you need to download and install a virtualizer.
I am on a Windwos10 Professional brand new installation, my choice went to VirtualBox v6.1.14 since it's the latest available, but it doesn't seem a good choice because when I run the Xilinx setup program, the software claims "an untested installation of Oracle VirtualBox was detected on your machine. You can continue with this installation, but this version is untested and unexpected results may occur", and in fact the installation completely fails at the end.
I tried VirtualBox v6.1.12, with the same result.
What should I do to install ISE v14.7?

Do I need to downgrade to a VirtualBox 6.0 package?
