Internet Explorer 10 64 bit standalone download

I need to down grade and install Internet explorer 10 64bit on two computers.
One has Windows 7 and the other is Windows 10. I know I can install IE 10 on the Win 7 computer. But I only found IE10 32 bit. MS removed the other files last year.
If I had the IE10 64bit standalone install. I could do a test to see if I can down grade Windows 10 from IE 11 to IE 10.
I know that older version of IE can be installed on Win 8, had customer do that with old Juno program that put something like IE 8 on the system over writing IE11.

Thanks
