ole2.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like ole2.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like sapisvr.exe - to follow. These files were created so that multiple programs (eg. Windows) could share the same ole2.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 ole2.dll is attempted to be loaded either when Windows is starting up, or in some cases already running. Some of the most common ole2.dll errors include:
- Access Violation at address - ole2.dll.
- ole2.dll could not be found.
- Cannot find C:\Windows\System32\ole2.dll.
- Cannot register ole2.dll.
- Cannot start Windows. A required component is missing: ole2.dll. Please install Windows again.
- Failed to load ole2.dll.
- The application has failed to start because ole2.dll was not found.
- The file ole2.dll is missing or corrupt.
- This application failed to start because ole2.dll was not found. Re-installing the application may fix this problem.
Your ole2.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows), or deleted by a malware infection. Furthermore, ole2.dll file corruption could be caused from a power outage when loading Windows, system crash while loading ole2.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.
