Hi, the handling of global parameters changed between 1.10 and 1.11. Please update the database on the existing computer, and export it afterwards to another computer. You can install both 1.10 and 1.11 on the same computer if you use the zip / archive version (on Windows), start openLCA 1.10, make a copy of the database, close openLCA 1.10 and open 1.11, and then open the copied database, a prompt will appear to indicate that this database must be updated, then please update.
Best wishes,
Andreas
