The correct file you need to d/l is dvdshrink32setup and is a zip file. Strongly believe all others are fakes, and much worse, some contain hidden bad stuff. Before going any further, suggest you do a full offline scan of your computer. This really depends on what protective software you are using, but now you can go and d/l the proper file.
DON'T be fooled by a newer version, as this product was abounded several years ago (and it still works).
PS Give revisited the article and as an after though, it might be a good idea to include a link to the site that contains the software, Mindblower!
