What are nullfilter.ax Error Messages?

Dynamic Link Library nullfilter.ax Errors

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

• Access Violation at address - nullfilter.ax.
• nullfilter.ax could not be found.
• Cannot find C:\Program Files (x86)\Photodex\ProShow Producer\nullfilter.ax.
• Cannot register nullfilter.ax.
• Cannot start ProShow Producer. A required component is missing: nullfilter.ax. Please install ProShow Producer again.
• Failed to load nullfilter.ax.
• The application has failed to start because nullfilter.ax was not found.
• The file nullfilter.ax is missing or corrupt.
• This application failed to start because nullfilter.ax was not found. Re-installing the application may fix this problem.

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