How to Troubleshoot Runtime ‘Error R6034’ on Visual C++

A runtime error is directly related to software or hardware devices in your system. When a hardware or software component is damaged, it prevents a particular program from running and causes an R6034 execution time error on your Windows 10 PC.

An r6034 runtime error appears with a detailed error message:

The application tried to load the runtime library incorrectly. Contact application support for more information.

When this error occurs, you lose information in the file you are working on. This type of error can also affect system performance and make it slow, which is very annoying. Because of this error, you cannot run your system normally because every time you try to do something, it gives a runtime error. This error message is very critical and dangerous for your system.

What causes runtime error R6034?

Outdated third-party browser: If you get this error when trying to access your browser’s extensions or add-ons tab, chances are that you are not using the latest version available.

Missing or damaged Microsoft Visual C++ 2010 Redist packages: It turns out that several missing or damaged Visual C++ Redist dependencies may well be responsible for this error code.

Conflict with third-party backup software: It turns out that you can also encounter this problem in cases where you previously installed third-party backup software that may conflict with the built-in backup service.

Lack of administrative access: According to many affected users, this problem can also occur due to a lack of permissions required by the application.

Damaged system files: In some cases, this problem can occur due to corrupted system files affecting the execution logs required for certain applications to run.

The conflict caused by an Apple support file: If you have iTunes installed on your computer, keep in mind that this problem may also be caused by a problem with Apple support files.

Launch a DISM scan

  1. Press WinKey + R to open the Run dialog box.
  2. Type “cmd” and press Ctrl + Shift + Enter at the same time.
  3. This will launch the Windows console with administrator privileges.
  4. Type the following text next to the flashing cursor and press Enter.
    Dism /Online /Cleanup-Image /CheckHealth
  5. This tool works the same way as the SFC, so wait until it finishes restoring the corrupted Windows image.
  6. Then reboot the computer to save your changes.

Reinstall the distributed Microsoft Visual C++ packages

  1. Open the Control Panel.
  2. Then click on Programs and Features.
  3. Find the “Microsoft Visual C++ Redistributable (x86)” program and right-click on it.
  4. Click on Change in the context menu.

  6. This tool will then start repairing the Microsoft Visual C++ Redistributable file.
  7. Once the corrupted file recovery is complete, restart your computer and check to see if the runtime error has been corrected.

Running applications as an administrator
