java -Xmx1g -jar muse-standalone.jar
The command should be run from the folder that muse-standalone.jar is present in.
• Double-clicking on the jar will NOT work, because it does not give the program an adequate amount of memory.
• The -Xmx1g option runs the Java program with 1 GB of memory.
• For extremely large email archives, you can try -Xmx2g, -Xmx4g, etc. to increase the amount of memory.
