iTunesAssist.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like iTunesAssist.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like APSDaemon.exe - to follow. These files were created so that multiple programs (eg. iTools) could share the same iTunesAssist.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 iTunesAssist.dll is attempted to be loaded either when iTools is starting up, or in some cases already running. Some of the most common iTunesAssist.dll errors include:
- Access Violation at address - iTunesAssist.dll.
- iTunesAssist.dll could not be found.
- Cannot find C:\Program Files (x86)\ThinkSky\iTools 4\iTunesAssist.dll.
- Cannot register iTunesAssist.dll.
- Cannot start iTools. A required component is missing: iTunesAssist.dll. Please install iTools again.
- Failed to load iTunesAssist.dll.
- The application has failed to start because iTunesAssist.dll was not found.
- The file iTunesAssist.dll is missing or corrupt.
- This application failed to start because iTunesAssist.dll was not found. Re-installing the application may fix this problem.
Your iTunesAssist.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with iTools), or deleted by a malware infection. Furthermore, iTunesAssist.dll file corruption could be caused from a power outage when loading iTools, system crash while loading iTunesAssist.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.
