Runtime errors can be a frustrating experience for Windows users, often leading to program crashes and error messages. In this comprehensive guide, we will delve into the various aspects of runtime errors, why they occur, and most importantly, how to resolve them effectively. By the end of this article, you’ll be equipped with the knowledge to tackle runtime errors like a pro.

Why Do Runtime Errors Occur?

Runtime errors are notorious for disrupting the smooth operation of software applications. Understanding their underlying causes is crucial to addressing and preventing them. Here are the primary reasons why runtime errors occur:

1. Memory Leak

A memory leak is perhaps the most common culprit behind runtime errors on Windows computers. It transpires when a program mismanages memory allocations, resulting in excessive RAM consumption without proper deallocation. Another scenario involves code trying to access an object in memory that no longer exists.

2. Programming Errors

Programming errors can also lead to runtime errors. During the development phase, debugging helps identify and rectify these issues. However, if a bug slips through the cracks and makes its way into the final release, it can trigger runtime errors. Developers often provide updates or patches to fix such errors.

3. Incomplete Installation

Incomplete installations can be a breeding ground for runtime errors. When installing a program, if the process is interrupted due to factors like power failures or system crashes, it can result in an incomplete installation. This, in turn, may cause runtime errors when attempting to run the program.

4. Corrupt Registry

A corrupted or damaged registry can wreak havoc on your system, leading to runtime errors among other issues. Manual alterations to the registry are a common cause of damage. Hence, it is crucial to exercise caution when editing registry keys, and always make backups before making any changes.

How to Resolve Runtime Errors

Now that we’ve identified the reasons behind runtime errors, let’s explore effective methods to resolve them. While the specific solution may vary depending on the error, here are some general steps you can follow:

1. Install the Latest Microsoft Visual C++ Redistributable Package

Some users encounter runtime errors after updating their Windows operating system. These errors often reference the “Microsoft Visual C++ Runtime Library.” To resolve them, follow these steps:

  • Launch the Control Panel and navigate to “Programs and Features.”
  • Locate “Microsoft Visual C++ Redistributable” in the program list and uninstall it.
  • Download the latest Microsoft Visual C++ Redistributable Package from the official Microsoft website.
  • Install the downloaded package and restart your computer.

This solution addresses issues related to missing or outdated runtime components.

2. Run DISM Command and SFC Scan

Running the System File Checker (SFC) and Deployment Image Servicing and Management tool (DISM) can help repair corrupted files and system image issues, respectively:

  • Open an elevated Command Prompt.
  • To run SFC, execute the command: sfc /scannow
  • To run DISM, use the command: DISM.exe /Online /Cleanup-image /Restorehealth

These tools utilize Windows updates to fix corrupted files and system images.

3. Troubleshoot in Clean Boot State

Sometimes, third-party or startup applications may be responsible for runtime errors. To identify and rectify this issue:

  • Perform a clean boot to isolate the problem.
  • Gradually enable startup items and services to identify the culprit.


Runtime errors can be frustrating, but with the right knowledge and troubleshooting steps, you can effectively address them and maintain a smooth-running Windows system. By following the methods outlined in this guide, you can resolve most runtime errors and ensure a hassle-free computing experience.
