GREN50.OLB is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like GREN50.OLB, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like wisptis.exe - to follow. These files were created so that multiple programs (eg. Microsoft Office Basic 2007) could share the same GREN50.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 GREN50.OLB 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 GREN50.OLB errors include:
- Access Violation at address - GREN50.OLB.
- GREN50.OLB could not be found.
- Cannot find C:\Program Files (x86)\Microsoft Office\Office12\GREN50.OLB.
- Cannot register GREN50.OLB.
- Cannot start Microsoft Office Basic 2007. A required component is missing: GREN50.OLB. Please install Microsoft Office Basic 2007 again.
- Failed to load GREN50.OLB.
- The application has failed to start because GREN50.OLB was not found.
- The file GREN50.OLB is missing or corrupt.
- This application failed to start because GREN50.OLB was not found. Re-installing the application may fix this problem.
Your GREN50.OLB 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, GREN50.OLB file corruption could be caused from a power outage when loading Microsoft Office Basic 2007, system crash while loading GREN50.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.
