0FC343C0.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like 0FC343C0.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. SoftEther VPN Client) could share the same 0FC343C0.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 0FC343C0.dll is attempted to be loaded either when SoftEther VPN Client is starting up, or in some cases already running. Some of the most common 0FC343C0.dll errors include:
- Access Violation at address - 0FC343C0.dll.
- 0FC343C0.dll could not be found.
- Cannot find C:\Users\Tester\AppData\Local\Temp\VPN_72D3\0FC343C0.dll.
- Cannot register 0FC343C0.dll.
- Cannot start SoftEther VPN Client. A required component is missing: 0FC343C0.dll. Please install SoftEther VPN Client again.
- Failed to load 0FC343C0.dll.
- The application has failed to start because 0FC343C0.dll was not found.
- The file 0FC343C0.dll is missing or corrupt.
- This application failed to start because 0FC343C0.dll was not found. Re-installing the application may fix this problem.
Your 0FC343C0.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with SoftEther VPN Client), or deleted by a malware infection. Furthermore, 0FC343C0.dll file corruption could be caused from a power outage when loading SoftEther VPN Client, system crash while loading 0FC343C0.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.
