im trying to execute the 2.0.2 .msi file that i downloaded from this site, but it doesnt work. like, i click the file and nothing happens. i've also downloaded the file multiple times to ensure that the download wasnt faulty, but all the results were the same: the file not booting up the installer menu.

 im running a windows vista computer, if that helps.

Works fine for me, on Windows 8.1. It may well be a Vista compatibility issue.

Asking for solutions or reporting it as a bug on their forum might be your best shot. I can't think of much else you could do, apart from upgrade Windows.
