Go back to basics:

instead of downloading an installer, download the Weka release as zip file, e.g.g, stable version/other platforms (this can be used on all platforms, it just doesn't integrate itself into your Desktop; also doesn't require any admin rights)
unzip the downloaded archive
open a terminal (command prompt if you are on Windows), navigate to the directory where you unzipped the archive to and then into the directory that contains the weka.jar file
start Weka from the terminal using this command:
```
java -Xmx2000m -jar weka.jar
```

You can then confirm the maximum memory in the GUIChooser:

Help -> System info
check value for memory.max
