3DSetup.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like 3DSetup.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. FIFA 2001) could share the same 3DSetup.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 3DSetup.dll is attempted to be loaded either when FIFA 2001 is starting up, or in some cases already running. Some of the most common 3DSetup.dll errors include:
- Access Violation at address - 3DSetup.dll.
- 3DSetup.dll could not be found.
- Cannot find C:\Program Files (x86)\EA SPORTS\FIFA 2001 Demo\3DSetup\3DSetup.dll.
- Cannot register 3DSetup.dll.
- Cannot start FIFA 2001. A required component is missing: 3DSetup.dll. Please install FIFA 2001 again.
- Failed to load 3DSetup.dll.
- The application has failed to start because 3DSetup.dll was not found.
- The file 3DSetup.dll is missing or corrupt.
- This application failed to start because 3DSetup.dll was not found. Re-installing the application may fix this problem.
Your 3DSetup.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with FIFA 2001), or deleted by a malware infection. Furthermore, 3DSetup.dll file corruption could be caused from a power outage when loading FIFA 2001, system crash while loading 3DSetup.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.
