I purchased an ADSP-21369 EZ-KIT Lite which i tried to install and it says it is only registered for 10 days.
We understand that you have not registered and validated your license yet. If so, you must register and validate your license
Can you please register the license serial number with the Host ID in the below link to receive the validation codes:
Locating the Host ID on your computer:
If using VisualDSP++ 4.0 or above: The Host ID is shown in the bottom right-hand corner of the Help->About->Licenses tab.
If using VisualDSP++ 3.5 or below: The Host ID can be found in the VisualDSP*.*\System subfolder, in the reg_info.txt file. If the reg_info.txt file does not exist, go to a DOS Command Prompt, change to the Operating System drive (usually the C:\ drive) and run the VOL command to display the Volume Serial Number. Use the Volume Serial Number as the Machine ID.
Please refer chapter "Validating a Node-Locked License" from the below link to validate your license:
