can't debug 64bit intel windows app on ARM CPU

[davecotter]

I have an ARM cpu, and have installed the ARM version of Windows. it has that "x86 emulation" built in so this *shouldn't" be a problem. but it is.

i've installed MSDev 2019 community edition, with a few extra individual components:

this config is EXACTLY the same as my intel computer's msdev installation.

When i go to look for Debuggers in the expected folder:

the folder is empty:

all the other folders DO have debugger files in them (x86, arm, arm64). the ONLY one that is empty is the x64 folder. which means Qt won't find it, which means i can't debug my Qt app.

i've seen this forum post, and i've done all the things it suggested by @Chris-Kawa:

but to no avail.

What am I missing?

I had to copy the c:\Program Files (x86)\Windows Kits\10\Debuggers\x64 directory from a different machine.

really? am I the only person to try this?

does nobody else have an M1 mac and Parallels, who develops for both mac and windows?

Hi, it looks like debugging 64-bit Intel apps on ARM is difficult/not yet supported, for example this page for .NET debugging exhibits the same problem (debugging currently not possible).

At https://bugreports.qt.io/browse/QTCREATORBUG-26934 I've uploaded a screencast showing a "Hello World" x64 application being debugged on a Windows 11 Arm64 machine.

I had to copy the c:\Program Files (x86)\Windows Kits\10\Debuggers\x64 directory from a different machine.

Hopefully works with other applications, not just a hello world one.

I ran across this problem yesterday and created a video with the latest comments from @cristian-adam in the bug you posted at https://bugreports.qt.io/browse/QTCREATORBUG-26934.

My video that I hopes help someone else:
