UserOOBE.dll.mui is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like UserOOBE.dll.mui, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like appidpolicyconverter.exe - to follow. These files were created so that multiple programs (eg. Microsoft Office Access 2010) could share the same UserOOBE.dll.mui 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 MUI 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 UserOOBE.dll.mui 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 UserOOBE.dll.mui errors include:
- Access Violation at address - UserOOBE.dll.mui.
- UserOOBE.dll.mui could not be found.
- Cannot find C:\Windows\Temp\527D94AF-D053-4381-B105-0D815D53791E\amd64_microsoft-windows-oobe-user.resources_31bf3856ad364e35_10.0.16299.402_en-us_68a45215d5dfdf9e\UserOOBE.dll.mui.
- Cannot register UserOOBE.dll.mui.
- Cannot start Microsoft Office Access 2010. A required component is missing: UserOOBE.dll.mui. Please install Microsoft Office Access 2010 again.
- Failed to load UserOOBE.dll.mui.
- The application has failed to start because UserOOBE.dll.mui was not found.
- The file UserOOBE.dll.mui is missing or corrupt.
- This application failed to start because UserOOBE.dll.mui was not found. Re-installing the application may fix this problem.
Your UserOOBE.dll.mui 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, UserOOBE.dll.mui file corruption could be caused from a power outage when loading Microsoft Office Access 2010, system crash while loading UserOOBE.dll.mui, 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.
