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 aren't compatible, if your computer has memory problems, or if the computer has been infected with malicious software. If a runtime error keeps occurring, follow these steps:

1. Install the latest updates for Windows and for the program displaying the error. Note that the update for the program might be listed as an optional update on the Windows Update page.

Click Start button then show all programs and open Windows Update.



2. Check Action Center for a solution to the program displaying the error.

When you have Windows Error Reporting turned on and a program stops working, a problem report is typically sent to Microsoft for more analysis. If a solution is available, or there are steps you can take to minimize the likelihood of the problem recurring, they'll be available in Action Center.

Click to Flag icon in Notification area to open Action Center.



3. Update and run your antivirus software. Windows doesn't come with antivirus software, but Action Center can often monitor the antivirus software that you or your computer manufacturer have installed.

4. Make sure your computer has at least 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.
