## Updating the Scan Engine Manually

Although Trend Micro recommends that you schedule ScanMail to perform automatic updates of the scan engine, you can do it manually, as shown below.

### Procedure

1. Download the latest scan engine from the Trend Micro website.

   - For 64-bit:
     `\Program Files\Trend Micro\Smex\engine\vsapi\latest\vsapi64.dll`
5. Extract the new scan engine files from their temp directory to:
