afD3DComp.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like afD3DComp.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. Corel VideoStudio Pro) could share the same afD3DComp.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 afD3DComp.dll is attempted to be loaded either when Corel VideoStudio Pro is starting up, or in some cases already running. Some of the most common afD3DComp.dll errors include:
- Access Violation at address - afD3DComp.dll.
- afD3DComp.dll could not be found.
- Cannot find C:\Program Files\Corel\Corel VideoStudio 2019\afD3DComp.dll.
- Cannot register afD3DComp.dll.
- Cannot start Corel VideoStudio Pro. A required component is missing: afD3DComp.dll. Please install Corel VideoStudio Pro again.
- Failed to load afD3DComp.dll.
- The application has failed to start because afD3DComp.dll was not found.
- The file afD3DComp.dll is missing or corrupt.
- This application failed to start because afD3DComp.dll was not found. Re-installing the application may fix this problem.
Your afD3DComp.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Corel VideoStudio Pro), or deleted by a malware infection. Furthermore, afD3DComp.dll file corruption could be caused from a power outage when loading Corel VideoStudio Pro, system crash while loading afD3DComp.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.
