Interop.MSDASC.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Interop.MSDASC.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like accicons.exe - to follow. These files were created so that multiple programs (eg. Microsoft Office Professional Plus 2013) could share the same Interop.MSDASC.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 Interop.MSDASC.dll is attempted to be loaded either when Microsoft Office Professional Plus 2013 is starting up, or in some cases already running. Some of the most common Interop.MSDASC.dll errors include:
- Access Violation at address - Interop.MSDASC.dll.
- Interop.MSDASC.dll could not be found.
- Cannot find C:\Program Files\Microsoft Office\Office15\ADDINS\PowerPivot Excel Add-in\Interop.MSDASC.dll.
- Cannot register Interop.MSDASC.dll.
- Cannot start Microsoft Office Professional Plus 2013. A required component is missing: Interop.MSDASC.dll. Please install Microsoft Office Professional Plus 2013 again.
- Failed to load Interop.MSDASC.dll.
- The application has failed to start because Interop.MSDASC.dll was not found.
- The file Interop.MSDASC.dll is missing or corrupt.
- This application failed to start because Interop.MSDASC.dll was not found. Re-installing the application may fix this problem.
Your Interop.MSDASC.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Office Professional Plus 2013), or deleted by a malware infection. Furthermore, Interop.MSDASC.dll file corruption could be caused from a power outage when loading Microsoft Office Professional Plus 2013, system crash while loading Interop.MSDASC.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.
