  2. Relaunch the problematic app where the error clr20r3 appears.

Fix #3: Run an SFC Scan

Do you suspect that corrupted system files are causing the error? Then the first step in fixing corrupted system files is using a tool called SFC. This stands for System File Checker and it does exactly what its name implies: It helps you check and fix system files.

To use SFC, you’ll need an administrator login. Follow these steps:

Fix #5: Reinstall the .NET Framework

The .NET Framework is a runtime environment that helps load and execute the different kinds of software that you install on your computer. It’s not something you can uninstall, but it is something you can reinstall if it’s corrupted or missing from your system.

To get rid of these errors, there are two ways to go about it: the Manual method or the Automatic method. The manual way involves locating and downloading the framework yourself before reinstalling it on your PC and restarting.

The automatic fix, on the other hand, involves using Microsoft’s own troubleshooter tool. We recommend giving both methods a try so you can choose which one works best for you! To reinstall the .NET Framework manually, do this:

  2. Wait for the process to complete.

Fix #6: Disable the DEP Process

One of the causes of the error is a process called DEP. However, it’s important to keep in mind that DEP is just a catch-all term for Data Execution Prevention and is essentially designed to protect Windows by preventing code-based attacks.

When DEP detects an attempt to execute a piece of code (like when you boot up your PC), it stops the request until certain steps have been completed and confirms that it’s safe to continue. While DEP has proven itself effective at preventing malware attacks, unfortunately, sometimes certain processes in Windows don’t play nice with DEP and cause problems—such as the clr20r3 error.

So, how do you disable it? In order to disable DEP on Windows, do this:

  1. Navigate to the Control Panel, then select the Administrative Tools tab.
  2. In the administrative tools window that appears, select the services tab and look for a service called Data Execution Prevention.
  3. Right-click on it and choose properties.
  4. Uncheck its startup type, which should be set as Automatic.
  5. Click OK to save changes.
  6. Next, you need to restart your PC.
  7. When done go back into Services and check again if DEP is enabled or not.

Fix #7: Uninstall Any Virtualization Software

Virtualization software is software that allows you to run multiple operating systems simultaneously. It does so by creating a virtual computer, either from scratch or using an existing computer, and running your operating system within it.

In order to achieve compatibility with all your other programs, virtualization software uses a feature called binary translation. Sometimes called binary emulation, binary translation effectively translates a program’s binary code into something else before executing it—in our case, x86 code. This causes compatibility issues.

At first glance it might not seem like you need virtualization software to run another operating system; however, unless you’re running legacy games or applications, virtualization is still a very valuable tool for gaming and productivity alike.

Depending on what virtualization software you’re using, uninstallation might not be quite as simple as uninstalling a normal application. Read on for our guide:

  1. First, open Programs and Features from the Control Panel. There you will see a list of applications installed on your PC.
  2. Now, find and uninstall VMWare Workstation or VMWare Player, VirtualBox, or Oracle VM VirtualBox virtualization software.
  3. If you’re not sure which one to uninstall go to Control Panel > System and Security > Program & Features > View Installed Updates section on your PC and look up corresponding virtualization software version number in Installed Updates windows.
  4. Uninstall it as described above.
  5. Finally, go to Control Panel again.
  6. Click Uninstall a program.
  7. Select the virtualization software in question again and click on Uninstall button.
  8. Restart your computer after uninstallation process is complete.

Fix #8: Disable or Uninstall Any Antivirus

Anti-virus software plays an important role in keeping your computer safe from viruses and other unwanted programs. If you’re constantly getting error messages that prevent you from using a program, it may be time to uninstall or disable your antivirus software.

When you uninstall an antivirus program, it no longer can block any applications. The antivirus will still be there if you decide you want to install it again later. You can temporarily disable your anti-virus software through its interface, but remember that re-enabling it might not help with issue if it was interfering with other programs.

Fix #9: Use a PC Repair Tool

A PC Repair is a powerful tool which allows you to easily and safely repair your system by fixing registry errors, the clr20r3 error, dll errors and all kinds of possible issues that prevent your PC from working as it should. Just download and install it in a few minutes, then use its intuitive interface to fix your problems.

What’s more, PC repair tools are 100% safe. And they don’t contain viruses or malware.

Here’s how:

  1. Press Win+R then type regedit in the Run dialog box
  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

Clear out all unnecessary DRM files and fix the errors with ease
