I want to know if someone knows how to successfully add a new MCU or device in Proteus that is not available in the existent libraries. I've tried downloading the ECAD files of PIC16FJ84 using the library loader but it's always getting error.
Your cracked version can not download. You have to manually add the model by pasting it in the models directory. Search in google for this model and if you find it(its a few files with different extensions) try some tutorial on how to add new part in Proteus(again in google).
