0xc000007b error code popped up after I upgraded from Windows 8.1 to Windows 10. Nothing like 0xc000007b on Windows 8.1 I stuck to for more than 2 years before I finally upgraded to Windows 10.

However, if you downloaded Windows 10 and some of your files such as game files like PES is saying the application is unable to start correctly, error 0xc000007b detected, here are fixes option you can take.

There is no need to downgrade your OS as this may not fix the files in your program folders. However, apart from using a repair utility or downloading an online file to replace corrupt folders, here are some fast approaches to fix the app was unable to start correctly on Windows 10 or Windows 8.1 on 32-bits or 64-bits.

If you try the first approach and it doesn’t work fix it, try the next one until the error code is cleared. However, if there is no disconnection while you are downloading Windows update, the first two approaches should probably work for you.

1. Restart your PC


If you are the type that loves to put your PC in sleep mode or hibernate for a long time, the first approach to undertake is to restart your PC.

Literally, without running into a 0xc000007b error, hibernating your PC more than usual can lead to some programs not running correctly most especially if your device is running on low configuration.

If you have games like Fortnite installed on your Windows PC you’d likely encounter the “app was unable to start correctly”.

Therefore, when the 0xc000007b start popping up on your 32-bits or 64-bits Windows OS, first go ahead and restart your PC to clear all stored caches first.

2. Run Software with Administrative Right

Some software that is not needed to be installed before use requires an administrative right. If the software in question is not an app that needed to be installed before use, you should consider running it with an administrative right.

It’s obvious that to install apps or software on Windows PC, administrative right is required. However, if this was not granted during the installation process or the software doesn’t need to be installed before use, such an app may require an administrative right to run correctly.

Grant Admin Right

Here is how to grant a software an administrative right on Windows OS

  1. Right-click on the software with the “0xc000007b” error
  2. Hover your mouse down to properties  and click on it
  3. Click on compatibility
  4. Scroll down and tick run this program as an administrator
  5. Tap Apply and click  OK
  6. Done

Now, if the program was not granted administrator right before it has it now. Go back to the program’s icon and tap it to see if the error still occur again

3. Upgrade or Reinstall the Program


Upgrading Windows OS  should bring comfort and more efficiency to your work on your PC. However, if after you upgraded your OS and the 0xc000007b error comes up, you also need to check whether the program is corrupt or you are running an older version which is not compatible with the new OS version.

Take for instance that you are running Windows 2000 or Windows 7 when Microsoft already has a reasonable number of Windows 10.1 users, there is a possibility that the program will have an issue working on the new environment if it’s not developed for it.

For this, you need the latest version of the program or try to reinstall the program again whether the offline installer will be of good use without downloading the newer version from the internet.

4. Reinstall Microsoft .NET framework


Check whether the Microsoft .NET framework is working fine on your device. In most case, the application was unable to start correctly is caused by the .NET framework.

While it’s very easy to fix the 0xc000007b not working correctly on Windows 8, 8.1, and Windows 10/10.1, Windows 7 or earlier version users have a lot of work to do fixing the application not working correctly as a result of the 0xc000007b error code.

However, to fix this using the Microsoft .framework follow the workaround below.
