A 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.
Runtime errors can occur if you are running two software programs that are not compatible, if your computer has memory problems, or if the computer has been infected with malicious software. If a runtime error keeps occurring, try these troubleshooting steps:
Install the latest updates for Windows and for the program displaying the error. To learn more about this, see How can I tell if my computer is up to date?
Report problems so Windows can notify you if solutions are available. To learn more about this, see Report problems and check for solutions automatically.
Check your computer for viruses and always run an antivirus program. To learn more about this, see How can I help protect my computer from viruses?
Make sure your computer has the minimum amount of random access memory (RAM) required to run the program that is displaying the error. Look for the program requirements online or in the packaging information. To learn more about computer memory, see View your computer information.
