Protect2f6221cc.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Protect2f6221cc.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Free Snipping Tool) could share the same Protect2f6221cc.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when Protect2f6221cc.dll is attempted to be loaded either when Free Snipping Tool is starting up, or in some cases already running. Some of the most common Protect2f6221cc.dll errors include:
- Access Violation at address - Protect2f6221cc.dll.
- Protect2f6221cc.dll could not be found.
- Cannot find C:\Users\Tester\AppData\Local\Temp\Protect2f6221cc.dll.
- Cannot register Protect2f6221cc.dll.
- Cannot start Free Snipping Tool. A required component is missing: Protect2f6221cc.dll. Please install Free Snipping Tool again.
- Failed to load Protect2f6221cc.dll.
- The application has failed to start because Protect2f6221cc.dll was not found.
- The file Protect2f6221cc.dll is missing or corrupt.
- This application failed to start because Protect2f6221cc.dll was not found. Re-installing the application may fix this problem.
Your Protect2f6221cc.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Free Snipping Tool), or deleted by a malware infection. Furthermore, Protect2f6221cc.dll file corruption could be caused from a power outage when loading Free Snipping Tool, system crash while loading Protect2f6221cc.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
