DIFF_MATCH_PATCH_WIN32.DLL is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like DIFF_MATCH_PATCH_WIN32.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. Microsoft Office 2016 Preview (32 bit)) could share the same DIFF_MATCH_PATCH_WIN32.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 DIFF_MATCH_PATCH_WIN32.DLL is attempted to be loaded either when Microsoft Office 2016 Preview (32 bit) is starting up, or in some cases already running. Some of the most common DIFF_MATCH_PATCH_WIN32.DLL errors include:
- Access Violation at address - DIFF_MATCH_PATCH_WIN32.DLL.
- DIFF_MATCH_PATCH_WIN32.DLL could not be found.
- Cannot find C:\Program Files (x86)\Microsoft Office\root\Office16\DIFF_MATCH_PATCH_WIN32.DLL.
- Cannot register DIFF_MATCH_PATCH_WIN32.DLL.
- Cannot start Microsoft Office 2016 Preview (32 bit). A required component is missing: DIFF_MATCH_PATCH_WIN32.DLL. Please install Microsoft Office 2016 Preview (32 bit) again.
- Failed to load DIFF_MATCH_PATCH_WIN32.DLL.
- The application has failed to start because DIFF_MATCH_PATCH_WIN32.DLL was not found.
- The file DIFF_MATCH_PATCH_WIN32.DLL is missing or corrupt.
- This application failed to start because DIFF_MATCH_PATCH_WIN32.DLL was not found. Re-installing the application may fix this problem.
Your DIFF_MATCH_PATCH_WIN32.DLL file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Office 2016 Preview (32 bit)), or deleted by a malware infection. Furthermore, DIFF_MATCH_PATCH_WIN32.DLL file corruption could be caused from a power outage when loading Microsoft Office 2016 Preview (32 bit), system crash while loading DIFF_MATCH_PATCH_WIN32.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.
