Installation on Windows 11 on Arm

I am using a Arm64-based PC running windows 11. I wanted to test if I can run JJazzlab through emulation provided by Windows 11 on Arm, but the installation failed: Image

Is there a way to bypass the system check and install JJazzlab?

no, only the x64 cpu architecture is supported (and also aarch64 for mac).

Hi Jerome, thank you for your response. To clarify, I wasn’t suggesting native support for Arm64 Windows 11. Instead, I was referring to running the existing x64 version of JJazzLab via Windows-on-Arm’s x64 emulation, which already works well in practice.

Actually, I manually copied the C:\Program Files\JJazzLab folder from an x64 PC to my Arm64 machine and successfully ran JJazzLab\bin\jjazzlab64.exe — it performed smoothly without issues.

So my suggestion would be to adjust the system check in the JJazzLab Windows installer to allow installation of x64 JJazzLab on both x64 and Arm64 Windows 11 systems. This would only require modifying the Windows installer, not the JJazzLab program itself.

Would this be feasible for a future version of JJazzLab? I’d be happy to provide additional details or test builds if helpful.

Ah ok. Yes indeed, I think I have just to change this in the InnoSetup config file. It is set to x64 right now, that explains your warning. I should use x64compatible instead.

Implemented for next release.
