## 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.

2. Extract the contents of the `engv_x64dll_v####-####.zip` file to a temporary directory.
3. Stop the following ScanMail services by clicking the Windows Start button and navigating to Programs → Administrative Tools → Services:
   - ScanMail for Microsoft Exchange Remote Configuration Server (ScanMail_RemoteConfig)
   - ScanMail for Microsoft Exchange Master Service (ScanMail_Master)
4. Back up the following scan engine file:
   - `\Program Files\Trend Micro\Smex\engine\vsapi\latest\vsapi64.dll`
5. Extract the new scan engine files from their temp directory to:
   `\Program Files\Trend Micro\Smex\engine\vsapi\latest\`
6. Start the ScanMail services:
   1. Click the Windows Start button, then Programs → Administrative Tools → Services.
   2. Right click each of the following ScanMail scan services and select Start in the pop-up menu that appears.
