On German Win XP, the DisplayFusion installer creates a start menu entry at "...\Startmenü\Programs\DisplayFusion" instead of "...\Startmenü\Programme\DisplayFusion".
Hi Cito, thank you for the feedback. Would you be able to uninstall DisplayFusion, re-download it and install the new build for me to confirm that it is working now? You can find the re-packaged version here (just click 'Download Now'):
