I cannot find a German/French/Spanish version of TweakMASTER 3.0
TweakMASTER 3.0 is available in English only right now. The localized versions will be offered at a later time, however anyone who buys a license to TweakMASTER 3.0 now, will be entitled to a free upgrade to any localized version of TweakMASTER 3.x when it is released.
