Hi,

4. Does the CD work on another computer?
Runtime error is a software or hardware problem that prevents a program from working correctly. Runtime errors might cause you to lose information in the file you're working on, cause errors in the file (corrupt the file) so you can't work with it, or
prevent you from using a feature. Unlike stop errors, runtime errors don't typically cause Windows or a program to stop working.
