An application that was unable to start correctly had an error code of 0xc00007b. An error code such as this indicates that your Windows files are corrupted or a DLL file from your application is missing. When you download something from an unauthorized source, you are likely to receive this error. Anti-virus engines often delete DLLs and prevent applications from running if they detect something suspicious.

If the correct redistributables are not installed on your computer, this error code will also occur. You will have problems running 32-bit applications if you do not have 32-bit DLLs. Then you’ll need to install all the VC runtimes.

As you’ll see in this article, there are several ways you can solve the 0xc00007b error code on your own. Our team has collected the best working

methods for you and presented them in a simple manner. The methods range from simple to advanced.

1. Repair Corrupt System Files

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

The “.dll” file that is supposed to be placed in System 32 folder seems to be the solution that works for some users. However, this solution needs to be applied very carefully since System 32 is a very sensitive folder containing the majority of Windows essentials.
