Well, I have 1.0.1 and 1.0.2 installed.
These are the "official" versions.
Then I tried yours.
I also have that "Maria Mole" installed.
As this one comes as a .exe I ran the install and let it do its thing.
It starts to load then simply puts that message on the screen.
The IDE is being launched from a shortcut - which it generated.
The version is the one at the start of this thread - which says no java.
