I am using VISTA and I got an error when using the parallel port

  WxPic need a detailed description of the components to program them. In order to get up-to-date descriptions, WxPic uses the files provided by Michochip in the MPLAB IDE.Those files being under Microchip copyrights, they cannot be provided in the WxPic installation. Therefore you must download them separately on the MPLAB page and then indicate to WxPic where those files are.
