Can't add pcb symbol to orcad pcb V17 lite

I think the issue you are seeing is because the allegro-builder.bat file is attempting to run just "allegro.exe", but you don't have the full license to run the Allegro PCB Editor.

The allegro-builder.bat file should contain lines that look like:

"allegro -s [file_name_pkg.scr]"

Where the file_name_pkg.scr is the footprint of the part you downloaded. Please try modifying the allegro-builder.bat file so that line instead reads:

"allegro -orcad -s [file_name_pkg.scr]"

The addition of the "-orcad" to the command tells allegro that it should run in "OrCAD mode". It may pop up a box after it starts that says "No Allegro OrCAD license found, enter Lite mode?". Click Yes and it should continue on to import the part in OrCAD PCB Lite.

Let me know if this resolves your issue!

Thanks,
Matt
