Q: I have recently reinstalled Windows / upgraded to a new PC. Now Gamestudio doesn't work anymore. I get a crash as soon as I start any project.
A. Check how the DEP (data execution prevention) is set in your Windows configuration. Go to My Computer / Properties / Advanced / Performance / Settings / Data Execution Prevention, and make sure that it's in its default setting ("For essential Windows programs and services only"). If you have a German computer, it's Arbeitsplatz / Eigenschaften / Erweitert / Systemleistung / Datenausführungsverhinderung, and must be set at "nur für erforderliche Windows-Programme und -Dienste aktivieren".
