Did exactly so (even on a fresh installed new Windows with no older version ever installed, but this was accidentally), and also - of course - did use the version from the mail. But no chance, it does not work!

Afar from this: the version attached at the mail is exactly the same as the one that can be downloaded from the web site. And yes, it's the actual version. But as I remind, I had the same problem since months ago with older versions, after several trials I gave up.

Somehow this is a little bit disappointing ...
