- Expand the server hostname and click Sites.
- Select the apropriate site:
- Click OfficeScan if the product is installed in IIS Virtual Website.
- Click Default Web Site if the product is installed in IIS Default Website.
- In Feature View, double-click MIME Types.
- Add a new MIME Type with the following properties:
- File name extension: "."
- MIME type: "application/octet-stream"
