Aero.msstyles is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like aero.msstyles, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like HelpPane.exe - to follow. These files were created so that multiple programs (eg. Microsoft Office Access 2010) could share the same aero.msstyles 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 MSSTYLES 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 aero.msstyles is attempted to be loaded either when Microsoft Office Access 2010 is starting up, or in some cases already running. Some of the most common aero.msstyles errors include:
- Access Violation at address - aero.msstyles.
- Aero.msstyles could not be found.
- Cannot find C:\Windows\Resources\Themes\Aero\aero.msstyles.
- Cannot register aero.msstyles.
- Cannot start Microsoft Office Access 2010. A required component is missing: aero.msstyles. Please install Microsoft Office Access 2010 again.
- Failed to load aero.msstyles.
- The application has failed to start because aero.msstyles was not found.
- The file aero.msstyles is missing or corrupt.
- This application failed to start because aero.msstyles was not found. Re-installing the application may fix this problem.
Your aero.msstyles file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Office Access 2010), or deleted by a malware infection. Furthermore, aero.msstyles file corruption could be caused from a power outage when loading Microsoft Office Access 2010, system crash while loading aero.msstyles, 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.
