What are np_digital_signature.dll Error Messages?


Dynamic Link Library np_digital_signature.dll Errors

np_digital_signature.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like np_digital_signature.dll, 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. Nitro Pro) could share the same np_digital_signature.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 np_digital_signature.dll is attempted to be loaded either when Nitro Pro is starting up, or in some cases already running. Some of the most common np_digital_signature.dll errors include:

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

CAUTION : We strongly advise against downloading and copying np_digital_signature.dll to your appropriate Windows system directory.
