Program Spartan6 eFUSE key in w10

I need help programing efuse registers on Spartan 6 from windows 10.

• We have plethora of boards designed with the Spartan 6.
• We are currently programming them with an old Windows XP machine which needs to be retired and replaced with windows 10.
• The new Xilinx Vivado software doesn't support Spartan 6.
• The Xilinx official installer for the legacy ISE software installs a Virtual Box VM but this can not program the efuse registers probably because it is 64 bit.
• I have also followed a hack shared on the forms to install iMPACT natively on windows 10, but this also can not access the efuse registers.
• I have tried burning the key from the new toolset Vivado, but the instructions reference changing settings in the implementation project which doesn't exist for an unsupported chip.

Further effort:

• I am attempting to build my own 32bit Linux VM with the software tools installed, but getting the cable driver working has eluded me so far.
• I may reinstall windows 10 as 32 bit.

Has anyone out there found a solution for programming Spartan 6 efuse registers from windows 10 or any other configuration?

I was able to build my own 32bit Linux VM and get it to program the eFUSE registers.

• I used Debian 10 32bit.
• The desktop has to be gnome classic or mate for the windows to work.
• The both Xilinx old driver and it's Vivado driver will not work. There is a third party driver with instructions here
