What are VSTOLoader.dll Error Messages?


Dynamic Link Library VSTOLoader.dll Errors

VSTOLoader.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like VSTOLoader.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Microsoft Visio Premium 2010) could share the same VSTOLoader.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 VSTOLoader.dll is attempted to be loaded either when Microsoft Visio Premium 2010 is starting up, or in some cases already running. Some of the most common VSTOLoader.dll errors include:

Your VSTOLoader.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Visio Premium 2010), or deleted by a malware infection. Furthermore, VSTOLoader.dll file corruption could be caused from a power outage when loading Microsoft Visio Premium 2010, system crash while loading VSTOLoader.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.
