Thank you this is super helpful.
This confirmed the model is good and something else was wrong.
So after googling "Expected device instantiation or directive here." I found others with the same problem and the solution.
Turns out, on older models, TI had some non printing character (alt code?) and a spare line feed at the end of their models. LT 24.0 didn't care, but 24.1 does care.
Deleting this character and the? the extra line feed from the model made this work. It also fixed other broken TI models I have.
Seems all the old stuff had this, but not the newer TI models.
?
thanx for the help.

I copied and pasted the TL074 model netlist into a schematic and used the opamp2 symbol renamed TL074. Added ¡À15V supplies and hooked it up as an inverting gain of -10 with two 10k resistors and it ran as expected.

Then I copied the model into a file and named it TL074.301(43) in the same directory with an ".inc TL074.301(43)" into the schematic. I commented out the netlist pasted into the schematic. It also ran.
