stshellex64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like stshellex64.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. SureThing CD Labeler Deluxe Edition) could share the same stshellex64.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 stshellex64.dll is attempted to be loaded either when SureThing CD Labeler Deluxe Edition is starting up, or in some cases already running. Some of the most common stshellex64.dll errors include:
- Access Violation at address - stshellex64.dll.
- stshellex64.dll could not be found.
- Cannot find C:\Program Files (x86)\Common Files\SureThing Shared\ShellExtension\stshellex64.dll.
- Cannot register stshellex64.dll.
- Cannot start SureThing CD Labeler Deluxe Edition. A required component is missing: stshellex64.dll. Please install SureThing CD Labeler Deluxe Edition again.
- Failed to load stshellex64.dll.
- The application has failed to start because stshellex64.dll was not found.
- The file stshellex64.dll is missing or corrupt.
- This application failed to start because stshellex64.dll was not found. Re-installing the application may fix this problem.
Your stshellex64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with SureThing CD Labeler Deluxe Edition), or deleted by a malware infection. Furthermore, stshellex64.dll file corruption could be caused from a power outage when loading SureThing CD Labeler Deluxe Edition, system crash while loading stshellex64.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.
