EVS Enterprise users can use software licenses installed on a C Tech Universal License Server to provide licensing to multiple users. Unlike USB license keys, software licenses are tied to the specific computer where the license server is installed.

Licensing Procedure
Here is how to request an Enterprise License:
EVS Enterprise licenses work through the C Tech Universal License Server like other EVS licenses, but are tied to the server’s hardware instead of a USB license key.
To request your purchased license, do the following:
- Run the C Tech License Manager
- You can do this on the server or any EVS client computer
- If you are using a client computer, you must set up the Servers Configuration first.
- Click the “Query Server” button
- In the query results window, you will see the “System Identifier”
- Click “Copy to Clipboard” to copy the full query results including the System Identifier
- You can do this on the server or any EVS client computer
Info
Your System Identifier will be unique to your computer.
Then email the System Identifier to sales@ctech.com along with the following information:
- System Identifier: (your identifier string)
- Company: (your company name)
- User: (your name)
- E-Mail: (your email address)
- Phone: (your phone number)
- C Tech’s Invoice number for your order (this is to ensure that you receive the proper licenses)
After verifying your information, C Tech will generate a license file and email it to the address you provided.
Once you receive the .ctupdate file, follow the included instructions to apply the update using the C Tech License Manager.
