Here are a few things to try:
Try bringing up Lattix by running the batch file “lattixarchitect.bat” in the Lattix bin directory.
If the error message suggests that you are running out of Java heap space, you can also try running “lattixarchitect.exe” with the argument “lattixarchitect.exe -Xmx1024m“.
Please contact us if you are not able to start up for any reason.
