PSRCHKEY.DAT is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like PSRCHKEY.DAT, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like accicons.exe - to follow. These files were created so that multiple programs (eg. Microsoft Office Professional Plus 2010 (64-bit)) could share the same PSRCHKEY.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 PSRCHKEY.DAT is attempted to be loaded either when Microsoft Office Professional Plus 2010 (64-bit) is starting up, or in some cases already running. Some of the most common PSRCHKEY.DAT errors include:
- Access Violation at address - PSRCHKEY.DAT.
- PSRCHKEY.DAT could not be found.
- Cannot find C:\Program Files\Microsoft Office\Office14\1033\PSRCHKEY.DAT.
- Cannot register PSRCHKEY.DAT.
- Cannot start Microsoft Office Professional Plus 2010 (64-bit). A required component is missing: PSRCHKEY.DAT. Please install Microsoft Office Professional Plus 2010 (64-bit) again.
- Failed to load PSRCHKEY.DAT.
- The application has failed to start because PSRCHKEY.DAT was not found.
- The file PSRCHKEY.DAT is missing or corrupt.
- This application failed to start because PSRCHKEY.DAT was not found. Re-installing the application may fix this problem.
Your PSRCHKEY.DAT file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Office Professional Plus 2010 (64-bit)), or deleted by a malware infection. Furthermore, PSRCHKEY.DAT file corruption could be caused from a power outage when loading Microsoft Office Professional Plus 2010 (64-bit), system crash while loading PSRCHKEY.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.
