-This is a known issue with the latest drivers released after version **v1.24**. The fast workaround in the previous setup was to revert the driver back to version 1.24. That version should be available in https://www.microchip.com/development-tools/pic-and-dspic-downloads-archive, but does not clearly appear in section "MPLAB C Compiler for PIC24 and dsPIC DSCs" and seems to be available only as "Source Archives".

 The peripheral libraries are no longer shipped with the compiler package. These may be downloaded separately from the MPLAB XC download page.
 ```
-So, the proper fix is to download the additional Legacy Peripheral Libraries as explained int the previous section.
