Win 10 arm PI 4

Question

Hi Guys, Ok well, all i am trying to do is install windows 10 arm onto an SD card, sounds easy, but i cant achieve it, so i downloaded the two files, the ARM and the other one, i have both of them on my laptop, i am using a windows 10 laptop HP g5 Pavilion, and the Raspberry PI is a 4, PI 4, so i open the WoR.exe program and it runs, i fill in all the stuff, then i get to the point where it asks me to put the ISO file in, i have tried different options but only one works, i think its UUP-converter-wimlib.7z, think that was the one, can anyone tell me if that is the right file, if not what and where is it, anyway it starts installing, says...formatting sd card, install windows, installing drivers, then at about 98% it comes up with installation failed cant find image file, then click cancel and it comes up with installation failure in red. i tried also using a flash drive usb stick and it does the same thing so its not the card, anyone any ideas please, tearing my hair out and haven't got much left lol...from Fred in Essex Uk.
