AppFormatCOM.Interop.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like AppFormatCOM.Interop.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Nero MediaHome 2019) could share the same AppFormatCOM.Interop.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 AppFormatCOM.Interop.dll is attempted to be loaded either when Nero MediaHome 2019 is starting up, or in some cases already running. Some of the most common AppFormatCOM.Interop.dll errors include:
- Access Violation at address - AppFormatCOM.Interop.dll.
- AppFormatCOM.Interop.dll could not be found.
- Cannot find C:\Program Files (x86)\Nero\Nero 2019\Nero MediaHome\AppFormatCOM.Interop.dll.
- Cannot register AppFormatCOM.Interop.dll.
- Cannot start Nero MediaHome 2019. A required component is missing: AppFormatCOM.Interop.dll. Please install Nero MediaHome 2019 again.
- Failed to load AppFormatCOM.Interop.dll.
- The application has failed to start because AppFormatCOM.Interop.dll was not found.
- The file AppFormatCOM.Interop.dll is missing or corrupt.
- This application failed to start because AppFormatCOM.Interop.dll was not found. Re-installing the application may fix this problem.
Your AppFormatCOM.Interop.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Nero MediaHome 2019), or deleted by a malware infection. Furthermore, AppFormatCOM.Interop.dll file corruption could be caused from a power outage when loading Nero MediaHome 2019, system crash while loading AppFormatCOM.Interop.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.
