I think it was because MPLABX downloaded the older version..I have tried the 2.4 libraries now ( 1 bluddy Gig).. Bigger than the MLA...
It's not as easy as MC said it would be... I have to set up a "BSP" so my hardware profile can be used... The biggest issue was that it doesn't work with C32... It has to be XC32..
I have it working on windows with 3.65 but my Linux box it can't find it just like what you was saying.
I didn't reinstall it with 4.01 it don't like the one that's with 3.65.
