Original issue reported on code.google.com by r.biedert on 7 Jul 2010 at 4:36

This is caused by changed COM GUIDs (as cited in the ReleaseNotes.rtf):

_All components' and interfaces' GUIDs in TetComp have been changed in order to 
be parallel installable with the version of TetComp bundled with Tobii Studio._

We should solve this in a way that the old and the new COM objects can be used 
both. Ideally transparently, if that's too hard then we just create a 2nd Tobii 
adapter.

Note, to solve this issue the library EyeTracker2Java has to be adapted, more 
specifically the package de.dfki.eyetracker.tetapi has to be regenerated.

Enhanced EyeTracker2Java with Tobii Api v5 and adjusted the tracking server to 
be able to switch between the old and the new Api.
Short term tests were successful, long term tests are still to do...
