Thanks a lot. But the .exe still crashes with the same message. I used the SET RESSOURCE OFF and ON with no result. I guess the resource file you're talking about is foxuser.dbf/.fpt (or one like that), and it looks ok. I'll try to do something with the configuration file, wich defines the temp directories. Do I need to include any dll/resource file in the project file or is it enough to put it in the same directory ?
