sab_mapi.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like sab_mapi.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like OneDriveSetup.exe - to follow. These files were created so that multiple programs (eg. SuperAntiSpyware Free Edition) could share the same sab_mapi.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 sab_mapi.dll is attempted to be loaded either when SuperAntiSpyware Free Edition is starting up, or in some cases already running. Some of the most common sab_mapi.dll errors include:
- Access Violation at address - sab_mapi.dll.
- sab_mapi.dll could not be found.
- Cannot find C:\Program Files\SUPERAntiSpyware\Plugins\sab_mapi.dll.
- Cannot register sab_mapi.dll.
- Cannot start SuperAntiSpyware Free Edition. A required component is missing: sab_mapi.dll. Please install SuperAntiSpyware Free Edition again.
- Failed to load sab_mapi.dll.
- The application has failed to start because sab_mapi.dll was not found.
- The file sab_mapi.dll is missing or corrupt.
- This application failed to start because sab_mapi.dll was not found. Re-installing the application may fix this problem.
Your sab_mapi.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with SuperAntiSpyware Free Edition), or deleted by a malware infection. Furthermore, sab_mapi.dll file corruption could be caused from a power outage when loading SuperAntiSpyware Free Edition, system crash while loading sab_mapi.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.
