Ah, thanks - I expected that there would also be some visible output on the
terminal, the download of this file was so fast, that I didn't notice it. ;)

I can confirm that it redownloads the executable each time when validating the
demo, here is an example diff: http://ix.io/dU5 .

In the meantime I've also tested with the Mafia II demo, but same result as
always: CEG executable, but works well in Wine...
