Have you heard of any resolution to this? Pitsco LEGO/Dacta is still shipping RoboLab 2.5.2, which only appears to include LabView 6.0.3, which in turn is not a version recognized on this site's support forms. (They go from 6.0.2 to 6.1...)
Also note that my install on Win2K didn't allow a "repair", just a "remove". I'll go back to 2.5.1 for now; any idea what was "fixed" or added in 2.5.2?
