What are vslangproj80.olb Error Messages?


Dynamic Link Library vslangproj80.olb Errors

vslangproj80.olb is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like vslangproj80.olb, 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. Microsoft Visual Studio 2010 Ultimate) could share the same vslangproj80.olb 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 OLB 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 vslangproj80.olb is attempted to be loaded either when Microsoft Visual Studio 2010 Ultimate is starting up, or in some cases already running. Some of the most common vslangproj80.olb errors include:

Your vslangproj80.olb file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Visual Studio 2010 Ultimate), or deleted by a malware infection. Furthermore, vslangproj80.olb file corruption could be caused from a power outage when loading Microsoft Visual Studio 2010 Ultimate, system crash while loading vslangproj80.olb, 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.

  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the vslangproj80.olb 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 vslangproj80.olb File (Caution: Advanced)

Download vslangproj80.olb Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying vslangproj80.olb to your appropriate Windows system directory. Microsoft typically does not release Microsoft Visual Studio 2010 Ultimate OLB files for download because they are bundled together inside of a software installer.
