  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.

Runtime error 13 can result from running two programs that are not compatible with each other. RAM issues and Malware are also possible causes of this error.

This error is basically one of the possible errors which appear when a program is not working correctly. It can be triggered only when you try to use a specific feature of a program.


Here are some ways to fix Runtime error 13 :

Restart The Computer

Try turning your computer off and on again. This may sound funny, but you can fix a lot of problems in Windows simply by restarting the computer. Please try and see if this fixes the problem.

Try Running Windows in Safe Mode

Please try running Windows in Safe Mode. This makes Windows start with the minimum drivers and services. This prevents most applications to load which usually causes problems if there’s a bug or malware present on the computer.

If this works then you’ll know that one of the device drivers or services was responsible for this error. In which case, you can try uninstalling or updating drivers to see if the problem goes away.

Scan Windows For Malware

Sometimes malware is responsible for programs not working and returning the runtime 13 error. You can try to fix this problem by using an Anti-Malware software program.

Please try scanning your computer with Malwarebytes Anti-Malware or any Anti Malware software that you prefer.
