ASP.TLB is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like ASP.TLB, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like CNFNOT32.EXE - to follow. These files were created so that multiple programs (eg. Microsoft Office Basic 2007) could share the same ASP.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 ASP.TLB is attempted to be loaded either when Microsoft Office Basic 2007 is starting up, or in some cases already running. Some of the most common ASP.TLB errors include:
- Access Violation at address - ASP.TLB.
- ASP.TLB could not be found.
- Cannot find C:\Program Files (x86)\Microsoft Visual Studio\COMMON\IDE\IDE98\ASP.TLB.
- Cannot register ASP.TLB.
- Cannot start Microsoft Office Basic 2007. A required component is missing: ASP.TLB. Please install Microsoft Office Basic 2007 again.
- Failed to load ASP.TLB.
- The application has failed to start because ASP.TLB was not found.
- The file ASP.TLB is missing or corrupt.
- This application failed to start because ASP.TLB was not found. Re-installing the application may fix this problem.
Your ASP.TLB file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Office Basic 2007), or deleted by a malware infection. Furthermore, ASP.TLB file corruption could be caused from a power outage when loading Microsoft Office Basic 2007, system crash while loading ASP.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.
