I am not sure why I was not able to import/restore a .zolca type database. It was from another PC (mac to windows). Same version of the openLCA software. Any suggestions?

"error in opening zip file" - it seems the zolca file is corrupted. Mac tries to support users by already modifying compressed files, this could be a reason. Maybe just retry, don't touch then the file on the Apple computer (e.g., backup to USB directly).

Hi, I am having the same trouble, this time in changing over to a new computer. The problems seem to be with Ecoinvent. First I copied over the zolca files, this didnt work. So I downloaded them again from Nexus and tried again, but this didnt work either. Uninstalled and reinstalled OpenLCA a few times. Im not sure what to try next. Any suggestions?
