makensis completed but installer not found at {}

Error message

makensis completed but installer not found at {}

What it means

Post-condition guard in bundle_windows_nsis: makensis exited successfully, but the expected NSIS installer executable is not found at the computed output path. The success status was misleading — the installer was written to a different location or filename than expected — and the input at fault is the expected output_path versus makensis's actual output.
