PcClean4.2

PcClean v4.2 cleans up a classic VM error users with updated java were receiving. This error wouldn't prevent PcClean v4.0 from running, but it's a minor inconvenience having to click "Ok" each time the program starts. Installer now automatically prompts to install to the Program Files directory. A shortcut will be part of the next release (possible start menu integration as well).
