This check is done after previous version (3.1) is uninstalled. I am not able to turn off running/suspended guests because no VirtualBox is installed at the moment. The solution is to install previous version (3.1) again, turn off guests and then install version 3.2.

Suggestion - do this check BEFORE you uninstall old version. "	defect	closed	installer	VirtualBox 3.2.0	worksforme			Windows	Linux
