libtex_base.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libtex_base.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like AppInstaller.exe - to follow. These files were created so that multiple programs (eg. MATLAB) could share the same libtex_base.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 libtex_base.dll is attempted to be loaded either when MATLAB is starting up, or in some cases already running. Some of the most common libtex_base.dll errors include:
- Access Violation at address - libtex_base.dll.
- libtex_base.dll could not be found.
- Cannot find C:\Program Files\MATLAB\R2019b\bin\win64\libtex_base.dll.
- Cannot register libtex_base.dll.
- Cannot start MATLAB. A required component is missing: libtex_base.dll. Please install MATLAB again.
- Failed to load libtex_base.dll.
- The application has failed to start because libtex_base.dll was not found.
- The file libtex_base.dll is missing or corrupt.
- This application failed to start because libtex_base.dll was not found. Re-installing the application may fix this problem.
Your libtex_base.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with MATLAB), or deleted by a malware infection. Furthermore, libtex_base.dll file corruption could be caused from a power outage when loading MATLAB, system crash while loading libtex_base.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.
