Error 0x000007b

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 to this problem, and we’re going to show them to you.


How do I 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

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.


2. Reinstall .NET Framework

  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.

The most common solution for this error is simply the 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.

3. Reinstall the troubled application

  1. In the Windows 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.

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.


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.

The 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.

5. 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.

Finally, this might seem like 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.


6. Run the 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.
