What are SUN.TLB Error Messages?

Dynamic Link Library SUN.TLB Errors

SUN.TLB is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like SUN.TLB, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like FileCoAuth.exe - to follow. These files were created so that multiple programs (eg. Command & Conquer: Tiberian Sun) could share the same SUN.TLB 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 TLB 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 SUN.TLB is attempted to be loaded either when Command & Conquer: Tiberian Sun is starting up, or in some cases already running. Some of the most common SUN.TLB errors include:

• Access Violation at address - SUN.TLB.
• SUN.TLB could not be found.
• Cannot find C:\Westwood\TS Demo\SUN.TLB.
• Cannot register SUN.TLB.
• Cannot start Command & Conquer: Tiberian Sun. A required component is missing: SUN.TLB. Please install Command & Conquer: Tiberian Sun again.
• Failed to load SUN.TLB.
• The application has failed to start because SUN.TLB was not found.
• The file SUN.TLB is missing or corrupt.
• This application failed to start because SUN.TLB was not found. Re-installing the application may fix this problem.

Your SUN.TLB file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Command & Conquer: Tiberian Sun), or deleted by a malware infection. Furthermore, SUN.TLB file corruption could be caused from a power outage when loading Command & Conquer: Tiberian Sun, system crash while loading SUN.TLB, 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.

If Windows Update failed to resolve the SUN.TLB error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

If Those Steps Fail: Download and Replace Your SUN.TLB File (Caution: Advanced)
