AIPreviewHandler.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like AIPreviewHandler.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 7za.exe - to follow. These files were created so that multiple programs (eg. Adobe Illustrator CC) could share the same AIPreviewHandler.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 AIPreviewHandler.dll is attempted to be loaded either when Adobe Illustrator CC is starting up, or in some cases already running. Some of the most common AIPreviewHandler.dll errors include:
- Access Violation at address - AIPreviewHandler.dll.
- AIPreviewHandler.dll could not be found.
- Cannot find C:\Program Files\Adobe\Adobe Illustrator CC 2019\Support Files\Contents\Windows\AIPreviewHandler.dll.
- Cannot register AIPreviewHandler.dll.
- Cannot start Adobe Illustrator CC. A required component is missing: AIPreviewHandler.dll. Please install Adobe Illustrator CC again.
- Failed to load AIPreviewHandler.dll.
- The application has failed to start because AIPreviewHandler.dll was not found.
- The file AIPreviewHandler.dll is missing or corrupt.
- This application failed to start because AIPreviewHandler.dll was not found. Re-installing the application may fix this problem.
Your AIPreviewHandler.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Adobe Illustrator CC), or deleted by a malware infection. Furthermore, AIPreviewHandler.dll file corruption could be caused from a power outage when loading Adobe Illustrator CC, system crash while loading AIPreviewHandler.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.
