What are Policy.12.0.Microsoft.Office.Interop.Access.Dao.dll Error Messages?


Dynamic Link Library Policy.12.0.Microsoft.Office.Interop.Access.Dao.dll Errors

Policy.12.0.Microsoft.Office.Interop.Access.Dao.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Policy.12.0.Microsoft.Office.Interop.Access.Dao.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like AppInstaller.exe - to follow. These files were created so that multiple programs (eg. Microsoft Visio Premium 2010) could share the same Policy.12.0.Microsoft.Office.Interop.Access.Dao.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 Policy.12.0.Microsoft.Office.Interop.Access.Dao.dll is attempted to be loaded either when Microsoft Visio Premium 2010 is starting up, or in some cases already running. Some of the most common Policy.12.0.Microsoft.Office.Interop.Access.Dao.dll errors include:

Your Policy.12.0.Microsoft.Office.Interop.Access.Dao.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Visio Premium 2010), or deleted by a malware infection. Furthermore, Policy.12.0.Microsoft.Office.Interop.Access.Dao.dll file corruption could be caused from a power outage when loading Microsoft Visio Premium 2010, system crash while loading Policy.12.0.Microsoft.Office.Interop.Access.Dao.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.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many Policy.12.0.Microsoft.Office.Interop.Access.Dao.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the Policy.12.0.Microsoft.Office.Interop.Access.Dao.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.
