What are desktopapi.tlb Error Messages?

Dynamic Link Library desktopapi.tlb Errors

desktopapi.tlb is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like desktopapi.tlb, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 710_b039_multilanguage.exe - to follow. These files were created so that multiple programs (eg. BlackBerry Desktop Manager) could share the same desktopapi.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 desktopapi.tlb is attempted to be loaded either when BlackBerry Desktop Manager is starting up, or in some cases already running. Some of the most common desktopapi.tlb errors include:

• Access Violation at address - desktopapi.tlb.
• desktopapi.tlb could not be found.
• Cannot find C:\Program Files (x86)\Research In Motion\BlackBerry Desktop\desktopapi.tlb.
• Cannot register desktopapi.tlb.
• Cannot start BlackBerry Desktop Manager. A required component is missing: desktopapi.tlb. Please install BlackBerry Desktop Manager again.
• Failed to load desktopapi.tlb.
• The application has failed to start because desktopapi.tlb was not found.
• The file desktopapi.tlb is missing or corrupt.
• This application failed to start because desktopapi.tlb was not found. Re-installing the application may fix this problem.

Your desktopapi.tlb file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with BlackBerry Desktop Manager), or deleted by a malware infection. Furthermore, desktopapi.tlb file corruption could be caused from a power outage when loading BlackBerry Desktop Manager, system crash while loading desktopapi.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.
