An unpatched Access 97 executable ( msaccess.exe ) will immediately crash on modern computers due to a famous bug known as the .
When Microsoft released Access 2000, they overhauled the file format and database engine. This update notoriously broke backward compatibility, slowed down file operations, and introduced file-bloat issues. Many developers refused to upgrade, locking their applications into the Access 97 environment forever. The Value of a "Portable" Architecture
