Answer 1

Hi, Julia libraries are making the calculation faster, if they are not present (haven't been downloaded yet) this is shown as error in the log file but does not lead openLCA to crash. There should be different messages in the log file that detail a crash (latest are at the bottom of the first page).

Comments

I am also getting similar issue. where to download libraries?
