Ok, next time go to Start/computer/choose the drive you want to search(say C:, for example), then use the search function next to the address bar. Also, FXpansions installer is fine. It either installs to The directories you've previously made or to .../program files(x86)/steinberg/VST/plugins (32bit version) or .../program files/steinberg/VST/plugins. You dont have to add the App path to Sonars VST search options.
