What are DxmAVSource.tlb Error Messages?

Dynamic Link Library DxmAVSource.tlb Errors

DxmAVSource.tlb is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like DxmAVSource.tlb, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 7za.exe - to follow. These files were created so that multiple programs (eg. Adobe Premiere Pro CC) could share the same DxmAVSource.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 DxmAVSource.tlb is attempted to be loaded either when Adobe Premiere Pro CC is starting up, or in some cases already running. Some of the most common DxmAVSource.tlb errors include:

• Access Violation at address - DxmAVSource.tlb.
• DxmAVSource.tlb could not be found.
• Cannot find C:\Program Files\Adobe\Adobe Premiere Pro CC 2019\Plug-Ins\Common\DxmAVSource.tlb.
• Cannot register DxmAVSource.tlb.
• Cannot start Adobe Premiere Pro CC. A required component is missing: DxmAVSource.tlb. Please install Adobe Premiere Pro CC again.
• Failed to load DxmAVSource.tlb.
• The application has failed to start because DxmAVSource.tlb was not found.
• The file DxmAVSource.tlb is missing or corrupt.
• This application failed to start because DxmAVSource.tlb was not found. Re-installing the application may fix this problem.

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