Are you using the same catalog with MaxIm? Visual PinPoint and MaxIm both use the same single instance of the PinPoint engine. If full PinPoint is installed, you'll notice that MaxIm has a few more options available. The solutions can be a bit different depending on the settings for sensitivity. Compare the number of stars used in the solution and check to see that you have the same catalog selected (and expansion factor) in both programs. PinPoint is an engine and has no "settings" itself, the settings must be provided by whichever program (MaxIm or Visual PP) is hosting the engine.
