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