How do you check if your MPLAB® XC compiler license is activated?

To check if your compiler license has been properly installed and activated, use the latest MPLAB® X IDE and go to Tools > Licenses > License Status.

Other ways to check that your license is properly installed:

  • In a command prompt, go to the bin folder in the MPLAB XC Compiler installation folder (e.g., C:\Program Files (x86)\Microchip\xc32\v1.20\bin>) and run xclm -status. This should provide you with the installed license information.
  • Try to compile a project that uses an optimization level greater than one in MPLAB X IDE. If you get a warning that you are using free mode and optimizations are not available in this mode, then you know that the license is not installed properly.
​

MPLAB XC8 Compiler has an option to run in Free mode even for Pro installed license, please check this mode in the 'Project Properties' under the 'XC8 Options'.
