Hi Friedrich,

thank you very much for your comments. We will definitely look into the UAC-aware section asap. As for now, our problem is solved. My colleague had implemented NLog into our program suite. The NLog configuration file was, by mistake, set to create log files directly into the application's base directory (in other words ProgramFiles\OurFolder) ...that's not a very good idea! :-) Turned the logger off and now everything runs fine again!
