VistaCalendar.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like VistaCalendar.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like regsvr32.exe - to follow. These files were created so that multiple programs (eg. Sony Ericsson PC Suite) could share the same VistaCalendar.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 VistaCalendar.dll is attempted to be loaded either when Sony Ericsson PC Suite is starting up, or in some cases already running. Some of the most common VistaCalendar.dll errors include:
- Access Violation at address - VistaCalendar.dll.
- VistaCalendar.dll could not be found.
- Cannot find C:\Program Files (x86)\Sony Ericsson\Sony Ericsson PC Suite\VistaCalendar.dll.
- Cannot register VistaCalendar.dll.
- Cannot start Sony Ericsson PC Suite. A required component is missing: VistaCalendar.dll. Please install Sony Ericsson PC Suite again.
- Failed to load VistaCalendar.dll.
- The application has failed to start because VistaCalendar.dll was not found.
- The file VistaCalendar.dll is missing or corrupt.
- This application failed to start because VistaCalendar.dll was not found. Re-installing the application may fix this problem.
Your VistaCalendar.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Sony Ericsson PC Suite), or deleted by a malware infection. Furthermore, VistaCalendar.dll file corruption could be caused from a power outage when loading Sony Ericsson PC Suite, system crash while loading VistaCalendar.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.
