2. The "64-bit" Angle
- SharePoint Designer 2010 was officially released only as a 32-bit application.
- However, it could install and run on 64-bit versions of Windows (7, 8, 10, 11) without issue via WOW64 (Windows-on-Windows 64-bit emulation).
- Why the title says "64bit": The installer package may be labelled as "64bit compatible" or someone has repackaged the 32-bit binaries into a wrapper that the user assumes makes it "64bit." There is no native 64-bit executable for SPD 2010.
5. If you genuinely need SPD 2010 functionality today
Here are legitimate alternatives:
1. Security Vulnerabilities

- You cannot connect to modern SharePoint Online sites.
- You risk exposing credentials to downgrade attacks.
- Antivirus software (Defender, CrowdStrike) will quarantine it immediately.
