I have a older thermostat that only has 2 wires, is the Google nest still compatible? Do I need to run a new wire?

Most of the time it is.

I have a 2 wire system also and the app is giving me an error stating I need a Common Wire.
Not sure where it would connect as there are only two wires attached to my furnace?
