Runtime error

Updated: 10/07/2019 by Computer Hope

When programming, we use a language to speak to the computer. That language has syntax. If the rules of the syntax are broken, then the compiler complains and throws a syntax error. In the same vein, all of the programming code that is written must be translated and compiled into something the computer can understand. If there are errors in that process, the compiler complains and throws a compiler error. These errors are given types, numbers, and brief English explanations. They offer the engineer a way to debug their program in an orderly fashion.

Windows Runtime error

Lastly as a program is running or during its runtime, it may encounter problems during execution. When a problem arises that the software cannot resolve, it throws a runtime error, which means, while I was running, I had a problem I could not resolve. The software, not the operating system, gives the error. Through a self-monitoring mechanism called a trap, the software diagnoses itself, realizes it cannot go on, and traps to a runtime error. There are many reasons why you may see a runtime error. The following are a few examples.

Poor programming

A runtime error can be caused by poor programming practices. If the engineer loads his software with memory leaks, it can cause a runtime error. If software patches are available, they can be installed to fix this problem. However, if no patches are available, there is no way to fix this problem since it lies in the software.

Other software

If there is a program running poorly on your computer, it can affect other programs. In a Windows environment, many things are shared, and if a rogue application loads, a runtime error can occur. In this case, you can shut down all other applications and then see if your software still has a runtime error.

Aging or damaged hardware

To a large degree, software depends on the workability of peripherals in your computer. If you have an older computer, your hard drive is older than two years, you have recently had an electrical storm, or the cooling fan is not working, degradation in service can occur. Any of these events can cause your software to throw a runtime error.

Virus or other malware

Viruses and other malware can run in the background undetected and can cause a lot of damage. They are not the leading cause of a runtime error, but can still lead to one. It's imperative you scan your system with some type of antivirus software daily.

These are only a few of the causes for runtime errors. In general, if you encounter an error in software that was recently installed, the software itself might be in error. For software that was running properly for some time, it might be your hardware. In this case, check your hardware, and scan for viruses.
