# Configuration Prerequisites

Before attempting to configure the server/client functionality, ensure that the following have been accomplished:

- Installation of the ViDi software on the server device and client devices.

- Connect the Cognex Dongle, with the client/server licenses, on the server device.

  Note:

  The following licenses must be present on the Cognex Dongle:

  - ViDi.Remote
  - ViDi.Remote.Service
  - ViDi.Remote.Client

  To ensure that the licenses are enabled, use the Wibu CodeMeter WebAdmin. The licenses will be listed in the License Monitoring tab. Contact your Cognex sales representative if they are not present.
