On page 255 of the data sheet it lists the picstart plus as a programmer that will work with it (the picstart works with any and all PIC chips). Try upgrading mplab and/or your firmware. There is usually a readme on MPLAB and PS+ which tells you which chips were added for which firware/software revisions, but I can't seem to locate mine right now. Good luck! -Adam Pretorius Johan * Spoornet wrote: >Hi, > >I have the labtool 48, Pic Start Plus and propic programmers but none >support the pic18F452.
