OK, thanks very much. Could you please elaborate where you got the OPA161x model from? I have the 1611 model here but when I insert it I get more errors.
Man, LTSpice sometimes is so picky, I actually don't like it. But no real (free of cost) alternative out there I guess 🙂

Thanks again. I dropped the OPA161x.LIB file into the same directory as your .asc file. Still get the missing "OPA161x" error message. If I include the lib file with ".lib OPA161x.lib" I can add the OPA161x symbols back in, but these seem to be very different from yours as the only have three pins (+/-in and out) but are missing the +/- supply voltage pins.
I forgot that you also need the symbol file which uses the lib. Place this in ...\LTspiceXVII\lib\sym\Opamps directory.
OK, now we seemed to be getting somewhere, the sim file now actually loads without any visible errors.
But when I run the transient sim:
Sorry to be bugging you so much, but this stuff is admittedly way over my head 🙁

If the simulation runs ok you can forget those error messages.
But as I said before you may run into convergence issues (timestep too small - error). Those are typically quite challenging.
