# Software Installation

To successfully install ViDi, perform the following:

1. Attach the Cognex Security Dongle to a USB port on the computer that will be used to develop the vision application.
2. Download the ViDi installer from the Cognex support page.
3. Run the ViDi installer and follow the prompts.

Note:

Choosing the Custom option will allow you to install selected features:

- The Wibu Runtime Server, which is needed to connect to the USB Cognex Security Dongle.
- The main ViDi application (this is required).
- The ViDi Developer API.

- The VisionPro, Designer and ViDi software require that a valid Cognex Security Dongle be installed during all phases of operation. Any attempts to temporarily remove, substitute, or share a Cognex Security Dongle may cause your system to operate incorrectly, and may result in the loss of data.

  When ViDi is configured for the Client/Server functionality, and a computer has been configured as a server, the Cognex Security Dongle must be attached to the server, but the client(s) does not need a Cognex Security Dongle.
