Answer 1

That happens when an admin has installed openLCA as exe / installer, then you do not have access to the program directory, where the memory settings are stored, in the ini file.

java.nio.file.AccessDeniedException: C:\Program Files (x86)\openLCA\openLCA.ini

=> either ask your admin to adjust the memory, or download and extract the zip archive version, in your user directory, where you have write access.
