Error 3: "The Microsoft.ACE.OLEDB.12.0 provider is not registered on the local machine."

• Cause: You installed the 64-bit driver but your calling app is 32-bit (or vice versa).
• Fix: Both the driver and the calling application must match bitness. Use syswow64\odbcad32.exe to manage 32-bit DSNs on 64-bit OS.

• Cause: The 2007 driver requires an older Windows Installer patch.
• Fix: Install KB933395 from Microsoft Catalog, then retry.

7. Troubleshooting

• “The ‘Microsoft.ACE.OLEDB.12.0’ provider is not registered”
  → Install the driver (32-bit for your app if app is 32-bit)
• Conflict with Office installation
  → You may need the “silent” install or the matching bitness
• Download link broken
  → Try the 2010 or 2016 version from Microsoft’s site instead
