Some Windows users complained that every time they try to open a particular program or game, an error 0x000007B occurs.

There are many reasons why this error message shows up, but there are also a couple of solutions for this problem, and we’re going to show them to you.

How to fix error 0x000007B in Windows 10

Table of contents:

  1. Make sure to use the right architecture
  2. Reinstall .NET Framework
  3. Reinstall the troubled application
  4. Install DirectX and redistributables
  5. Run the installer in the compatibility mode
  6. Run the Troubleshooter
  7. Run SFC scan
  8. Run DISM

Solution 1 – Make sure to use the right architecture

As we said, various factors could cause this error, but the most common one is mixing 32bit and 64bit environments. For example, when 32bit application loads a 64bit DLL, error 0x000007B will show up.

For that purpose, we strongly advise you to run the respective installer which fits your current system architecture. By doing so, you’ll avoid the issue at hand. Most of the applications come with both x64 and x86 installers, respectively.

Solution 2 – Reinstall .NET Framework

The most common solution for this error is simply re-installation of .NET Framework.

You can easily download .NET Framework 4.5 installation from this link, but if you’re using an older version, just browse the internet for the proper installation file.

If the .NET Framework 4.5 is below the minimum requirements, make sure to download the latest release. Once you’ve installed it, the program should be able to start without retreating to the Error 0x000007B.

In case you’re not certain how to download and install .NET Framework, follow the instructions we provided below:

  1. Navigate to the official Microsoft site, here.
  2. Scroll to the bottom and select the .NET framework installer.
  3. Download Runtime and not Developer versions.
  4. Run the installer from the download menu and install it.
  5. Side note: If it get’s stuck, don’t worry — the installation will continue eventually.

Solution 3 – Reinstall the troubled application

If the re-installation of .NET Framework didn’t work, you can try to re-install a program or game which gives you this error.

It maybe sounds like a shabby solution, but there’s a possibility that installation wasn’t completed successfully, and some data files are missing.

Reinstalling the troubled application should resolve the majority of system-imposed issues. If you’re unsure how to reinstall an application clean, follow these instructions:

  1. In the Widnows Search bar, type Control and open Control Panel.
  2. Open Uninstall a program from the Category view.
  3. Uninstall the troubled program and restart your PC.
  4. Run IObit Uninstaller Pro or any other similar uninstalling tool to remove remaining files and registry inputs.
  5. Install the program and look for changes.

Solution 4 – Install DirectX and redistributables

Since we’re talking about re-installations, you can as well try to re-install Microsoft Visual C++. You can download it from this link.

We advise you to install the latest Microsoft Visual C++ Redistributable and the one which covers the game release date. So, for example, if your game dates to 2014, make sure to acquire the C++ 2013.

And finally, the last re-installation on our list is the re-installation of DirectX.

New installation of DirectX will only work if some game is giving you a 0x000007B error message, because as you probably know, DirectX is crucial feature for running a lot of games.

Sometimes, even though your DirectX installation is up to date, you’ll need to install the one which is provided with the game.

Some games require DirectX 9.0c, even though you have, say, Windows 10 with functional DirectX 11.

Solution 5 – Run the installer in the compatibility mode

Finally, this might seem as a long shot but the compatibility issues are far from uncommon on the Windows platform. In order to avoid that, you can run the installer or respective applications in the compatibility mode.

This should help you skip some hurdles imposed by the system, especially UAC and its limitations.

Here’s how to run the installer in the compatibility mode:

  1. Right-click on the installation setup file (most of the time it has the EXE extension) and open Properties.
  2. Select the Compatibility tab.
  3. Check the ”Run this program in compatibility mode for” box.
  4. From the drop-down menu, select an older Windows iteration.
  5. Check the ”Run this program as an administrator” box.
  6. Confirm changes and try installing the program again.

Solution 6 – Run the Troubleshooter

The next thing we’re going to try is Windows 10’s bulit-in troubleshooting tool. Here’s how to run Windows 10 Troubleshooter:

  1. Go to the Settings app.
  2. Head over to Updates & Security > Troubleshooting.
  3. Find Program compatibility troubleshooter and click it.
  4. Now, go to Run the troubleshooter.
  5. Follow further on-screen instructions and let the wizard find any issues.
  6. Restart your computer.

Solution 7 – Run SFC scan

If none of the solutions above got the job done, we’re going to try with yet another troubleshooting tool.

The SFC scan is a built-in feature designed to deal with various system problems, so it might be useful in this case.

Here’s how to run the SFC scan:

  1. Go to Search, type cmd, and open Command Prompt as Administrator.
  2. Enter the following line and press Enter: sfc/scannow
  3. Wait for the process to finish.
  4. Restart your computer.

Solution 8 – Run DISM

And finally, the last thing we’re going to try is running the DISM:

  1. Go to Search, type cmd, and open Command Prompt as Administrator.
  2. Enter the following command on the command line:
      • DISM.exe /Online /Cleanup-image /Restorehealth
  3. In case the DISM can’t obtain files online, try using your installation USB or DVD. Insert media and type following command:
      • DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess
  4. Make sure to replace ”C:RepairSourceWindows” path of your DVD or USB.

That would be all, I hope that at least one of these many re-installations will help you to solve the problem with error 0x000007B.
