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