A huge thank you to you both! It works perfectly; I have the .cof file, and I can access VSM debug mode in Proteus. That's great! Sorry again for not understanding right away. I tried to edit the file, but I didn't have the "open with" option; I clicked "edit." If this helps anyo...

I uninstalled and reinstalled PIC 8-bit toolchain, and it's the same; I still don't have the file with the .cof extension.
