Par2Calc.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Par2Calc.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. UseNext by Tangysoft) could share the same Par2Calc.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 Par2Calc.dll is attempted to be loaded either when UseNext by Tangysoft is starting up, or in some cases already running. Some of the most common Par2Calc.dll errors include:
- Access Violation at address - Par2Calc.dll.
- Par2Calc.dll could not be found.
- Cannot find C:\Program Files (x86)\UseNeXT\Par2Calc.dll.
- Cannot register Par2Calc.dll.
- Cannot start UseNext by Tangysoft. A required component is missing: Par2Calc.dll. Please install UseNext by Tangysoft again.
- Failed to load Par2Calc.dll.
- The application has failed to start because Par2Calc.dll was not found.
- The file Par2Calc.dll is missing or corrupt.
- This application failed to start because Par2Calc.dll was not found. Re-installing the application may fix this problem.
Your Par2Calc.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with UseNext by Tangysoft), or deleted by a malware infection. Furthermore, Par2Calc.dll file corruption could be caused from a power outage when loading UseNext by Tangysoft, system crash while loading Par2Calc.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.
