Control.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Control.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. Adobe Shockwave Player) could share the same Control.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 Control.dll is attempted to be loaded either when Adobe Shockwave Player is starting up, or in some cases already running. Some of the most common Control.dll errors include:
- Access Violation at address - Control.dll.
- Control.dll could not be found.
- Cannot find C:\Windows\SysWOW64\Macromed\Shockwave 10\Control.dll.
- Cannot register Control.dll.
- Cannot start Adobe Shockwave Player. A required component is missing: Control.dll. Please install Adobe Shockwave Player again.
- Failed to load Control.dll.
- The application has failed to start because Control.dll was not found.
- The file Control.dll is missing or corrupt.
- This application failed to start because Control.dll was not found. Re-installing the application may fix this problem.
Your Control.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Adobe Shockwave Player), or deleted by a malware infection. Furthermore, Control.dll file corruption could be caused from a power outage when loading Adobe Shockwave Player, system crash while loading Control.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.
