Unable to run an impact calculation

Question

Hello,

I started using Open LCA and I have a problem that I can't solve when I run an impact calculation.

Every time I run a calculation an error message appears, indicating a lack of memory. As recommended in the tutorial, I tried to increase the maximum memory used but the change does not register. A new error message appears, indicating an error in the "open log file". Below, a capture of the "Log file" tab :

As database I use Ecoinvent 3.7 and as LCIA method "openLCA LCIA methods v2.1.2" from Nexus.

Has anyone had this problem before? Thanks in advance.

Hi, I canot see the picture for some reason,

the change does not register

indicates however that the change is not done - you need to have write access for the folder where openLCA.exe is, so either apply as admin or install (i.e. unzip) the zip version of openLCA in your user directory.

Best wishes,

Andreas
