Sure, thanks for the trouble

Windows 64bits

Gretl 2023c

Well, gretl 2023c isn't released yet, so you're apparently running a snapshot, but that shouldn't typically be a problem. But which Windows _version_ , like 7, 8, 10, 11?

Can you install any other function package? If not, it's probably best to re-install gretl itself first.

cheers
