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