Hi Judy
thanks for the update and yes I have renamed the libcrypto_1_1. dll as in the previous post. how do I close the preferences page that loads ? We are using Windows 10, if we wanted to update Chemkin would it need a full version update eg Ansys 2024 r2 ? 
 chemkin as students are going to complain about it. ? Ive attached the screen.
