Spybot Search & Destroy 1.5.1.17 Beta

This is the full installer for all the bugs fixed and new features implemented since 1.5.1.15.

The installer has been updated a bit: InnoSetup 5.20 now (no idea if it fixes the floating point problems), I've improved all the localization stuff and had to move a few things around, but in general everything should be available in every language in the installer now, and I've also included the Explorer context menu option "Erase with Spybot" and the separate shredder.
