Obtain a LIC for Computers Not Connected to the Internet...

  1. From another computer that is connected to the Internet, visit the web page and enter the requested product information. The Computer ID (CID) must be obtained from the dialog File — License Management... of the target computer where the license will be installed.
  2. On the target computer, continue with the steps 1, 2, 3, and 6 of the section above.


  • Owners of a dongle-protected node-locked (Single-User) license must download and install the Sentinel Dongle Driver. Verify your dongle with the Dongle Testing Application. Additional information is available at LICENSE: Usage of a LPT-Dongle protected product.
  • Compatible product versions can be licensed with the same LIC on the same machine. The versions must be installed in different root folders. In this case, uninstall previous LICs and request a new LIC with the latest PSN and the latest software version. Then, the new LIC can be used to activate all versions that you want to use.
  • If the PSN is missing, contact the Keil Software Sales Department or the local Keil Software Distributor.
  • Do not change any Network Connection on the target computer during the registration process. The CID encodes various parameters including network adapter information. After product activation, the network adapter may change as it is the case on Notebooks with various network connections.
  • The CID encodes several computer parameters including a time stamp. This causes the CID to change daily. However, a LIC can be installed at any time, provided that the same Network Connection is active.
