In most cases, runtime errors are actually problems in your Windows system rather then the program trying to operate and is subsequently causing the error message.
A common source of runtime errors is a corrupt registry which causes programs to malfunction. For example, the runtime error #7 which means a memory problem may not really have anything to do at all with a shortage of memory on your computer - rather is could be a problem resting in the file structure of your computer which causes your program to malfunction.
