You will encounter the following terms as you install and license Keil products:

  • CID (Computer ID)
    The CID is a 10-character alphanumeric value that uniquely identifies your computer. It is automatically generated by the µVision IDE and is used to generate the LIC required for product activation. The File — License Management... dialog displays the CID for your computer.
  • PSN (Product Serial Number)
    The PSN is a 15-character alphanumeric value that you receive from Keil Software with your Keil product. The PSN is required to license and activate your product. The PSN and CID are used to generate a LIC.
  • LIC (License ID Code)
    The LIC is a 30-character alphanumeric value that is used to activate your Keil product. You must register on-line using your CID and PSN to obtain a LIC.
  • URL; Flex-URL (Uniform Resource Locator)
    The URL to the server that hosts the Flex License. This URL is required when using a Flexera Software licensing solution. The URL should have the form portNumber@serverName.
  • UNC (Universal Naming Convention)
    UNC is a machine-independent file naming convention. For example, the UNC path for a floating-license file named keilfloat.FLF on a shared folder named flic on a computer named serv1 is: \\serv1\flic\keilfloat.FLF.
