SecurePlatformToolkit64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like SecurePlatformToolkit64.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. Nokia Software Updater) could share the same SecurePlatformToolkit64.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 SecurePlatformToolkit64.dll is attempted to be loaded either when Nokia Software Updater is starting up, or in some cases already running. Some of the most common SecurePlatformToolkit64.dll errors include:
- Access Violation at address - SecurePlatformToolkit64.dll.
- SecurePlatformToolkit64.dll could not be found.
- Cannot find C:\Program Files (x86)\PC Connectivity Solution\SecurePlatformToolkit64.dll.
- Cannot register SecurePlatformToolkit64.dll.
- Cannot start Nokia Software Updater. A required component is missing: SecurePlatformToolkit64.dll. Please install Nokia Software Updater again.
- Failed to load SecurePlatformToolkit64.dll.
- The application has failed to start because SecurePlatformToolkit64.dll was not found.
- The file SecurePlatformToolkit64.dll is missing or corrupt.
- This application failed to start because SecurePlatformToolkit64.dll was not found. Re-installing the application may fix this problem.
Your SecurePlatformToolkit64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Nokia Software Updater), or deleted by a malware infection. Furthermore, SecurePlatformToolkit64.dll file corruption could be caused from a power outage when loading Nokia Software Updater, system crash while loading SecurePlatformToolkit64.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.
