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

0xc00007b “the application was unable to start correctly”. This error code represents that there is something corrupted within your Windows files or a DLL file from your application files is missing. This error is really common if you are downloading something from an unauthorized source. A lot of Anti-virus engines delete the DLLs and block the application from running if they detect something suspicious.

This error code can also be triggered if you don’t have the correct redistributables installed on your computer. This can be really confusing because if you are trying to run a 32-bit application and you don’t have 32-bit DLLs you will have problems running that application. In that case, you will have to install all the VC runtimes.

  1. Navigate to the location of the application and right-click on its main executable.
  2. Select “Properties” and then click on the “Compatibility” tab.
  3. In the compatibility tab, click on the “Run this Program in Compatibility Mode For” dropdown and select “Windows Vista” or any other version of Windows.

11: Installing “.dll” file (Only for VLC)

There seems to be a very specific solution for some users where they have been able to fix this issue by downloading and placing the “.dll” file in their System 32 folder. But this solution needs to implied with a lot of caution because System 32 is a very sensitive folder and it contains the bulk of the Windows essentials. Therefore, perform this at your own risk since “.dll” files from the internet can often be infected. In order to proceed:

  1. Download the libvlc.dll file from the internet.
  2. Navigate to the download location of the file and copy it using “Ctrl” + “C” after selecting it.
  3. Navigate to the following location.
  4. Press “Ctrl” + “V” in here to paste this file inside the folder.
  5. Allow any UAC prompts to confirm the action and check to see if the issue persists.

Note: Also, try to delete the shortcut that you are using to launch the application and create a new one.

12. Properly Reinstalling Windows VC Runtimes

This issue is also caused when your VC Runtimes are not properly installed or they have been corrupted. You can follow these steps to completely remove them from your computer and then reinstall every single one of them.

Once you uninstall all the VC Runtimes use this command to clean up your WinSxS Component store.

  1. Press and hold the Windows key then press the “X” key to open the Start Menu.
  2. Now click “PowerShell (Admin)” or “Command Prompt (Admin)”
  3. Type this command in the Command Prompt and press enter.
