libidn2-0.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libidn2-0.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like help.exe - to follow. These files were created so that multiple programs (eg. GIMP) could share the same libidn2-0.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 libidn2-0.dll is attempted to be loaded either when GIMP is starting up, or in some cases already running. Some of the most common libidn2-0.dll errors include:
- Access Violation at address - libidn2-0.dll.
- libidn2-0.dll could not be found.
- Cannot find C:\Program Files\GIMP 2\bin\libidn2-0.dll.
- Cannot register libidn2-0.dll.
- Cannot start GIMP. A required component is missing: libidn2-0.dll. Please install GIMP again.
- Failed to load libidn2-0.dll.
- The application has failed to start because libidn2-0.dll was not found.
- The file libidn2-0.dll is missing or corrupt.
- This application failed to start because libidn2-0.dll was not found. Re-installing the application may fix this problem.
Your libidn2-0.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with GIMP), or deleted by a malware infection. Furthermore, libidn2-0.dll file corruption could be caused from a power outage when loading GIMP, system crash while loading libidn2-0.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.
