Surely on some occasions when you have tried to run a program in Windows, it throws an error message. There are times when this message is due to a specific software malfunction, but it can also be due to an error in the program code.

When a program enters an infinite loop, that is, it cannot terminate it under any conditions, a runtime error is also generated. These errors are known as runtime error or runtime error. If you want to know the characteristics of this type of errors, and some mechanisms to try to avoid them, I invite you to continue reading. We already started.

What is a runtime error

A run-time error It is a type of error thrown by a software when it is started or during its execution. When this type of error occurs, the running program fails and hangs, displaying the error message and ending its execution.

The format of the error is generally the same. For systems with a specific Spanish language, it is shown in the following way:

Run-time error:

If the default language of the operating system is English, we would see the message:

Runtime error!

Why does a run-time error occur?

A run-time error it can occur for many reasons. For example, a wrong data type validation of a field in a software can generate this type of errors. If a field expects a value of only numbers and letters, and an alphanumeric character is entered, then the software issues a runtime error.

On the other hand, there are also the so-called infinite cycles. During software programming, iterations can be made to go through lists of values ​​or perform the same calculation operation on several values. These cycles have a condition which tells you that they must end. When exact conditions are given in which nOnce said stop condition will be fulfilled, the software enters an infinite loop of execution. This situation also generates a run-time error and hangs.

There are other reasons why a run-time error can be generated, below, we present the most common ones.

Run-time error due to memory leak

A memory leak error is the Most common runtime error due to hardware performance. This error occurs when a program is making inefficient use of the RAM. Programs have to use the amount of memory they need and free it up so that it is available to other programs. In the event that a program fails to free up RAM due to some error, a run-time error may occur.

It may also be the case that the program need to access a system resource and it cannot be loaded into memory. This situation also generates a run-time error.

Programming errors

During application development, programmers have to validar and debug all the functionalities of the application. In case some type of error is overlooked, it is carried over to the deployment phase of the tool. These errors in the validations and execution of the programs can generate errors in execution time.

To fix this type of error, when it occurs, software development companies generally they release update patches. Once the application is installed, we run the patch and it is updated and corrects the error.

Installation or update errors

If when we are installing an application a failure occurs and the installation closes, it is likely that the software is installed with problems. This can occur due to a power failure or an unexpected reboot of the system. In this case, if the application can be run, it is likely to throw a runtime error at some point.

In the same way, during the process of updating an application we must ensure a power source of back, like a battery. Since, if the computer shuts down during the update, errors may be generated in the application and it may not work correctly.

Errors in the system log

A mishandling the Windows registry can lead to application errors and that they throw an error at runtime. The most common cause of registry errors is the manual change of the values ​​of some keys.

If you are not familiar with using the Windows registry, avoid making any changes to this operating system tool. In case it is essential to make a change in the registry, it is recommended to rcarry out a security salvo of it. This way, if you make any mistakes, you can restore it to a working version.

How to repair runtime errors

There are several types of runtime errors. Therefore, there are also many methods to repair them. Here we describe three generic methods to try to fix these errors. These examples are made in Windows 10 operating system.

Update the Microsoft Visual C ++ Redistributable Package

It is possible that after updating Windows 10 we will find a runtime error related to Visual C ++ Redistributable package that we have installed. This can happen because the package has not been updated correctly.

Visual C ++ Redistributable Package Runtime Error

This package provides classes and tools that allow you to compile code for some applications and the operating system. If, in the last system update, some resource from the Visual C ++ package needs to be used and cannot be found, a run-time error is generated.

To solve this we just have to install the latest version of the package. First, we turn to Control Panel, we select the option Uninstall a program and we look for the installation of Microsoft Visual C ++ Redistributable that we have installed. We right click on it and select the uninstall option.

Uninstall Visual C ++ Redistributable Package.

In the installation wizard we follow the steps until we uninstall the tool.

Once the uninstallation is complete, we look for the latest version of the package on the official Microsoft website and install it. With this simple step the error should be solved.

Using the DISM and SFC command to troubleshoot runtime error

The DISM and SFC commands allow you to repair or fix errors in system files which may be causing runtime errors.

The SFC system file checker takes care of scan and repair damaged files from backup in the computer. On the other hand, the tool DISM deployment image maintenance and management repairs corrupted system files from a Windows image.

To use them open the Windows console with administrator privileges. Then write sfc / scannow and hit Enter.

To use the other tool type DISM.exe / Online / Cleanup-image / Restorehealth.

In the latter case, you need to have a system image mounted on some system drive.

Perform a clean boot of the system

A clean boot of the system is a load with a minimal set of drivers and applications. This type of load is similar to Windows safe mode, but with a greater number of functionalities. This makes it possible to diagnose and isolate what is the cause of the error at runtime.

To perform a clean boot, we write “System configuration” in the start menu. In the tab general we select the option Selective start and we just check the box Load system services.

Detect runtime error by clean boot.

Next, we go to the tab Services and here we press the button Disable all. We press Apply and Accept in that order.

Clean boot.

Finally, we go to the task manager (Ctrl + Shift + Esc) and we go to the tab Beginning. Here we select each of the programs that start with Windows and put them in the state Disabled

Detect runtime error by clean boot.

We restart the computer and it will perform a clean boot as soon as it is executed. This type of startup will allow you to identify if a third-party or startup program is the cause of the runtime error.
