problem with ctREFPROP #472

Closed cryosolver closed 2 years ago

cryosolver commented 2 years ago

Hello

I installed ctREFPROP via "pip install ctREFPROP" and then tested the following example. cryosolver1

I get this message when I run the example. cryosolver2

How can I solve this? Is the ctREFPROP installation not enough? Should I do something else? I am new to this software, hence my questions;

Many thanks in advance!

RPPREFIX should point to the location of your REFPROP installation. On windows, you shouldn't need to change it as it is fixed by the installer and you can comment out that line.

Did you install REFPROP? ctREFPROP is only a wrapper around REFPROP, you still need to purchase and install REFPROP
