Windows ARM architecture support for CoApp

[etxaleku]

Your question

Is there an ARM64 (aarch64) version of the CoApp for Windows? I see one for Linux but I can't seem to find one for Windows (11).

Addon & CoApp version and details

Hi,
All CoApps are here: https://github.com/aclap-dev/video-downloadhelper/wiki/CoApp-Installation

There doesn't appear to be arm for windows here https://github.com/aclap-dev/vdhcoapp/releases
Click show all 26 assets.

I tried clicking on "Show All Assets" and I do see the ARM versions for Linux and Mac, but as @Mattmjs mentioned there is not one for Windows ARM.

Even though there is no arm version, you can run x86 apps on Arm systems based on a web search.
It's not a native app for your hardware but what will it hurt to try. You should give it a try and see how it goes.

@Mattmjs, I know what you mean about the x86-emulation available under arm but I've had very bad experience "just trying that" as the hurt was pretty intense - I had to reinstall Windows and all my apps in order to restore my system to normal operation. I had installed a Brother all-in-one printer software package (for x86) and after trying that (it didn't work) then my Windows Update was broken and a reinstall was required to fix it. :(

@etxaleku
That's understandable if the experience wasn't too good with the printer. You could test drive it in Windows Sandbox to see if it will run properly. This won't interfere with your windows installation. You'll be able to determine if it's satisfactory or not.
It won't save anything once the sandbox is closed. Beyond that I put a question to ai for other options, see the response.

can x86 installer be converted to arm installer

Yes, but it depends on the installer and the software itself. Here are some key considerations:

Recompilation: If you have access to the source code, the best approach is to recompile the software for ARM architecture.

Emulation: Windows on ARM supports x86 emulation, meaning some x86 installers might work without modification

Repackaging: Some tools allow repackaging x86 installers to work on ARM, but compatibility isn't guaranteed

@Mattmjs Yes, and it’s that Recompilation approach that I’m hoping will happen… ARM/aarch64 platforms are becoming more popular, with many software products/projects providing the (re-)compiled software in ARM format so I created this issue in hopes that the CoApp project team would take the same approach. Unless there’s some very low level very hardware specific things going on in CoApp this should basically just be another compilation in the build process, this time specifying the ARM architecture (https://learn.arm.com/install-guides/gcc/cross/). And if CoApp is currently available for M-series Macs I suspect the cross-compilation is already being done for those builds. For background, I imagine an x86 installer can be converted to an arm installer if there are no binaries involved in the distribution – if there are binaries involved then a (cross-)compilation from source of all the binaries is a hard requirement. Although I guess the converted installer could install the x86 binaries and arrange that they run under emulation but as you mentioned the best approach is recompilation. In the Windows world the emulation seems to work reasonably well for Windows and Windows apps but once you cross over into Linux on WSL things get a good bit sketchier.
