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