5.1.3 Can I Install More Than One Version of the Same Compiler?

The compilers and installation process have been designed to allow you to have more than one version of the same compiler installed. In MPLAB X IDE, you can easily switch between compiler versions by changing options in the IDE. For details, see the following section in this user’s guide:

How Can I Select Which Compiler Version to Build With?

Compilers should be installed into a directory that is named according to the compiler version. This is reflected in the default directory specified by the installer. For example, the MPLAB XC16 compilers v1.00 and v1.10 would typically be placed in separate directories, as shown below:

C:\Program Files\Microchip\xc16\v1.00\

C:\Program Files\Microchip\xc16\v1.10\
