LICENSE: WHAT IS A CID?
Information in this article applies to:
- C51 Version 8
- C166 Version 6
- C251 Version 4
- CARM Version 2
QUESTION
What is the Computer Identification Number (CID)? Why does it change?
ANSWER
The CID is a 10-digit, alphanumeric number, generated by µVision, that contains parameters (hard disk ID, MAC address, operating system information) which uniquely identify your workstation. The Keil Product Licensing web pages use this information to construct your LIC.
The CID also contains current date information, so it changes daily. The changing date will not affect your LIC, so you may re-install a LIC at a later date on the same workstation.
MORE INFORMATION
- Refer to Terminology in the Licensing User's Guide.
