1 About the Installer and License Manager

This topic introduces the installers and license managers used in conjunction with MPLAB® XC C Compilers.

MPLAB XC C Compilers

Please see the MPLAB XC C compiler web page on the Microchip website for free compiler downloads and documentation concerning these compilers. Purchasing a PRO compiler license gives you increased levels of code optimization.

MPLAB XC Installer

The GUI installer will install a Free compiler (an MPLAB XC compiler in Free mode) on your PC. After the installation, you can purchase a PRO license to enable:

• PRO mode: advanced optimizations and other features.
• Functional Safety: PRO mode + functional safety operation.
• MPLAB Analysis Tool Suite: full code coverage, MISRA check, and thread safety check.

The installer is supported by the operating systems supported by the compilers. See your compiler documentation release notes for supported operating systems.

Licensing
