EZwave Memory limitation Error

I am using HyperLynx 9.2 on windows 10.

When I tried to check the simulation with EZwave , it shows up the message dialog as follow

"Memory Warning

Ezwave has almost reached the memory allocation limit

You can try to free memory by deleting waveforms or closing databases

In case of error, you can try to increase the memory limit:

1- setenv AMS_USE_ENV 1

2- setenv AMS_JAVA_MEMORY_HEAP "-Xms100M -Xmx1500M"

3- exit and re-run the simulation"

Do any one know how to increase memory of HyperLynx 9.2 windows version??

Thanks
