Hi, interesting question. For Windows, it is not really needed (everyone can install him or herself a version, as zip) but you can try to install the zip version in the public documents folder. In both cases (different users having installed their version in their account as zip or openLCA in public documents) you need to move the database folder to a location accessible for everyone (check other posts about this). But: then others might mess with your models etc. Better is a separate installation and separate databases for different users, and ideally use the LCA Collaboration Server for exchange across a team. Thank you!
