Windows error at runtime : "No native build was found"

• Version: 21.2.0

• Target: nsis:ia32

I’m packaging a Windows 32bit (as well as x64) application from an x64 AppVeyor VM with Node x64. My app has a dependency on leveldown v5.0.2 which does not provide 32bit prebuilt binaries anymore.

As can be seen in the following logs, electron-rebuild seems to succeed at compiling it itself:

However, when the app is launched on a x86 Windows, it fails with the following error:

Error: No native build was found for runtime=electron abi=70 platform=win32glibc arch=ia32

This seems to happen when we load leveldown.

I couldn’t find any solution to this problem and figured this could be a configuration problem when running electron-builder for another architecture.

Released leveldown 5.6.0 with a 32-bit Windows prebuild.
