(About 10% of the time I get bad network connections; this might be the actual trigger.)
Retrying after submitting the original message and I get the wizard. Indeed looks like an intermittent bad connection gives an NPE.

Looking at the code I guess the window is null when I try to open the error dialog, hence the window.getShell() call which fails.
The Modeling Discover wizard gets an NOE while diagnosing problems see below.
I started with a Win 64 Modeling EPP. Installed Acceleo (in response to a newsgroup query) Restarted Uninstalled Acceleo Restarted Invoked Help->Instal Modeling Components ... nothing ... NPE in error log
