Description:
The Windows x64 MSIX installer for v2.1.0 fails to install with error 0x80073CFD. Investigation shows the package has no digital signature at all (SignatureType: None), which Windows requires for MSIX installation regardless of Developer Mode settings.
Steps to reproduce:
- Download PearPass-Desktop-Windows-x64-v2.1.0.msix from the official website (pass.pears.com) or GitHub Releases
- Verify SHA256 checksum matches the published value (confirmed matching: 9a678bb8e62b4808da435a75a6af179606b50e8bf0f6da878bbd55da8c92ea2a)
- Enable Windows Developer Mode
- Run: Add-AppxPackage -Path "PearPass-Desktop-Windows-x64-v2.1.0.msix"
Expected: Package installs successfully
Actual: Installation fails with error 0x80073CFD
Diagnostic output:
Get-AuthenticodeSignature shows:
- Status: UnknownError
- StatusMessage: The form specified for the subject is not one supported or known by the specified trust provider
- SignatureType: None
- SignerCertificate: (null)
File properties in Windows Explorer confirm no "Digital Signatures" tab exists at all.
Environment:
- Windows 10
- File verified as authentic (SHA256 matches official release)
This appears to be a packaging/signing issue on the release side, not a corrupted download.
