Where is the ML10X editor?

I’m completely new to the morningstar-world and there is so much to learn…
Is it true that there is an editor for ML10X only when you are online? No desktop editor to install? In any case, I can’t find one on the homepage (unlike the MS6PRO)

Hi. Just click on the install icon when you’re on the web Editor as shown below, and the application will be downloaded for offline use.
