It's possible that 64bit version has been there but I don't remember seeing it there a week ago.
Build Number: 22.214.171.124
Build Date: 22-Mar-2013
McAfee Stinger detects and removes prevalent Fake Alert malware and threats identified in the "List Viruses" section of the Stinger application. While not a replacement
for full fledged antivirus software, Stinger is updated multiple times a week to include detection for newer Fake Alert variants and prevalent viruses.
... The current Build Number and Date are always in the Stinger Release Notes on the right side.
