Unsupported architecture for Windows

Error message

Unsupported architecture for Windows: ${architecture}

What it means

After validating the OS and architecture, normalizePlatform additionally enforces that Windows installs are amd64 only. A Windows arm64 (or ia32) target throws a dedicated error, since the release matrix only ships windows/amd64 binaries.

Solutions

1. Use an amd64 Windows machine or an x64 emulation layer is not supported — run Nasiko from a linux/amd64 environment instead (e.g. WSL2, container)
2. Check the qualification matrix for a future windows/arm64 release
3. In CI, pick a windows-latest amd64 runner

Example fix

// before
normalizePlatform('win32', 'arm64'); // on Windows ARM
// after
// run inside WSL2:
normalizePlatform('linux', 'arm64');

if (process.platform === 'win32' && process.arch !== 'x64') {
  console.error('Nasiko supports Windows amd64 only; use WSL2 or a container on ARM.');
  process.exit(1);
}

function isWindowsAmd64(platform, architecture) {
  return (platform === 'win32' || platform === 'windows') && (architecture === 'x64' || architecture === 'amd64');
}

try {
  const rel = getQualifiedRelease(version);
} catch (e) {
  if (e.message.startsWith('Unsupported architecture for Windows')) {
    console.error('Run Nasiko under WSL2 (linux) or on an amd64 Windows host.');
  } else throw e;
}

When it happens

Trigger: Calling normalizePlatform (via getQualifiedRelease/installer) on a Windows machine with process.arch other than 'amd64' — typically 'arm64' on Windows-on-ARM laptops.

Common situations: Windows ARM (Snapdragon) laptops trying to install Nasiko; CI on windows-arm64 runners; tests passing windows+arm64 combinations explicitly.
