Thanks I will try that. I wonder if when the next stable release ships if there could be a check if gnuplot 5 fails, then try 4.7? I'm not sure if shipping with both versions of gnuplot would be practical? Or even possible? Anyway, I ran into this when I needed to re-run some old code that I could have just updated.

Gretl is not specifically designed to support multiple installations, but it should be possible to "fake" it. Try deleting C:\Users\Logan Kelly\AppData\Roaming\gretl\.gretl2rc before starting gretl.
