How to Fix Error 0xc00007b “The Application was unable to start correctly”

Method 1. Repair Corrupt System Files

We stated at the beginning of the book that this problem is most commonly caused by a corrupted file or a different operating system bit. As a result, in this approach, we will demonstrate how to fix corrupted files.

Please keep in mind that there are many distinct versions of every app, and that most operating systems are designed on 32bit and 64bit platforms. So, first and foremost, determine which Bit OS your Windows is. To do so, go to Control Panel > System and Security > System. There is a system type listed there:

As you can see in the image above, my System type is 64Bit, hence my PC is only able to install 64bit applications. You can also verify your PC’s System type and then install the software of the correct bit.

Method 2. Run The Program As Administrator

The error 0xc00007b can occur when the application or game you’re attempting to launch requires administrator access. You can grant the programme the necessary permissions by allowing administrator rights.

To enable administrator rights, perform the following steps:

1. Right-click on the application or game icon and select Properties.
2. Click the “Properties” drop-down menu.
3. Go to the “Compatibility” tab in the Properties box.
4. Check the box next to “Settings” that says “Run this programme as an administrator.”
5. Click “Apply” and then “OK”.

By granting administrator permissions to your programme or game, you enable it to access system resources and do actions that might otherwise be limited.

Remember that enabling admin access should only be done if you trust the application or game and understand the hazards of running it with higher privileges.

Now that we’ve covered Method 3, let’s look at some alternative options for resolving issue 0xc00007b!

If the app is now working smoothly, it signifies that it required Administrator access to function properly. You can also configure the app to “Run as administrator” by default. When you enable this command, the software will always run as Administrator.

Next, get a new copy of the application or game installer and download it from a trustworthy source. Choose a version that is compatible with your operating system.

Run the installer after downloading and follow any on-screen prompts to reinstall the software or game on your computer. Once finished, relaunch it to verify if the error has been repaired.

Reinstalling an application or game can frequently resolve problems caused by corrupt files. It ensures a clean installation of all required components and, in most cases, fixes compatibility issues as well.

Remember to back up any vital data related with that specific application or game before proceeding with this technique in case anything goes wrong during reinstallation.
