Status:
Adware

Explanation:
The setup file is part of the Soft32.com download and install manager. It is an ad-supported installer and attempts to get the user to install various adware toolbars, browser add-ons, game applications or other potentially unwanted programs. If a sponsored software offer such as a toolbar is installed it might change the User’s home page, default search settings and 404 traffic. Note, the software installed by Soft32 is probably safe, just the installer is unwanted.

Description:
This 'download manager' is also considered bundleware, a utility designed to download software (possibly legitimate or opensource) and bundle it with a number of optional offers including ad-supported utilities, toolbars, shopping comparison tools and browser extensions.
