Verify what you downloaded

Each release lists the installer's SHA-256 checksum. Compare it with the file you downloaded, for example with PowerShell:

Get-FileHash .\PROOFDESK-Setup.exe -Algorithm SHA256

Signed builds show a digital signature under File Properties → Digital Signatures. Builds without a signature are labeled "unsigned" in the release notes.
