>I have two applications (executable), the first one is for logging in and checking latest version of the main application (the second one). Users get an error message "File Access Denied" whenever the program tries to overwrite the latest version of the main application (before launching it), even tho I have the code !attrib -r (file.exe) in the program. Looks like the code doesn't work. Why? It worked fine in FoxPro 2.6.

My guess is, the exe is already running when you try to copy over it...
