Does anyone know why Sigil installation stops if installing on Windows 24|H2 on an Arm64 processor and it says can only be installed on x64 machines? Microsoft have included an "emulator" in Windows 24H2 that allows regular x64 applications to run on Arm64 processors (in much the same way as the WOW layers allowed 32 bit applications to run on 64 bit processors). It is called Prism. I think Prism intercepts the x64 bit instructions and spits out Arm64 instructions to the cpu - something like that anyway. It is quite transparent to the user, it just works and on my ASUS vivobook S15 Arm64 machine and other x64 applications I have installed work a treat. Prism doesn't work on drivers however.

I am wondering what Sigil is doing that won't run on windows 24H2 on an arm processor?

If all that has happened is Sigil developers have "assumed" it won't work, but not tried it then I would like to. Any chance? If it has been tested and failed, an explanation would be nice. Off hand I can't think of anything Sigil might be doing that would not run with Prism.
