Quark sometimes provides older versions to registered enterprise customers.

If you obtain an installer from a non-official source (not recommended), here’s how to check its integrity:

| Step | Action | |------|--------| | 1 | Check file extension — official Quark installers are .exe (Windows) or .dmg (Mac). | | 2 | Verify digital signature — Right-click file → Properties → Digital Signatures. Must show “Quark Software Inc.” | | 3 | Scan with updated antivirus and Malwarebytes. | | 4 | Compare file hash with official MD5/SHA256 (only Quark support can provide these). |

Remember: No third-party “verified” badge on a random download site is trustworthy.

The Passport edition was a special international version of QuarkXPress (from versions 4 through 10). It included:

The Passport edition required a separate license and was more expensive than the standard edition. It was discontinued after QuarkXPress 10. Modern QuarkXPress (2015–2024) includes multilingual support in all versions.

Thus, searching for a “Passport download” for versions 41, 50, or 61 is pointless — those versions don’t exist, and the Passport branding is obsolete.
