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