pdf4exp.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like pdf4exp.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Capture.exe - to follow. These files were created so that multiple programs (eg. PDF ReDirect) could share the same pdf4exp.dll 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 DLL 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 pdf4exp.dll is attempted to be loaded either when PDF ReDirect is starting up, or in some cases already running. Some of the most common pdf4exp.dll errors include:
- Access Violation at address - pdf4exp.dll.
- pdf4exp.dll could not be found.
- Cannot find C:\Program Files (x86)\PDF reDirect\pdf4exp.dll.
- Cannot register pdf4exp.dll.
- Cannot start PDF ReDirect. A required component is missing: pdf4exp.dll. Please install PDF ReDirect again.
- Failed to load pdf4exp.dll.
- The application has failed to start because pdf4exp.dll was not found.
- The file pdf4exp.dll is missing or corrupt.
- This application failed to start because pdf4exp.dll was not found. Re-installing the application may fix this problem.
Your pdf4exp.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with PDF ReDirect), or deleted by a malware infection. Furthermore, pdf4exp.dll file corruption could be caused from a power outage when loading PDF ReDirect, system crash while loading pdf4exp.dll, 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.
