Nitro_KissMetrics.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Nitro_KissMetrics.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 PDF Reader (64-bit)) could share the same Nitro_KissMetrics.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 Nitro_KissMetrics.dll is attempted to be loaded either when Nitro PDF Reader (64-bit) is starting up, or in some cases already running. Some of the most common Nitro_KissMetrics.dll errors include:
- Access Violation at address - Nitro_KissMetrics.dll.
- Nitro_KissMetrics.dll could not be found.
- Cannot find C:\Users\Tester\AppData\Local\Temp\NitroPDF_KM_ec16f0fa2cadde062ccce4b22a906fda\Nitro_KissMetrics.dll.
- Cannot register Nitro_KissMetrics.dll.
- Cannot start Nitro PDF Reader (64-bit). A required component is missing: Nitro_KissMetrics.dll. Please install Nitro PDF Reader (64-bit) again.
- Failed to load Nitro_KissMetrics.dll.
- The application has failed to start because Nitro_KissMetrics.dll was not found.
- The file Nitro_KissMetrics.dll is missing or corrupt.
- This application failed to start because Nitro_KissMetrics.dll was not found. Re-installing the application may fix this problem.
Your Nitro_KissMetrics.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Nitro PDF Reader (64-bit)), or deleted by a malware infection. Furthermore, Nitro_KissMetrics.dll file corruption could be caused from a power outage when loading Nitro PDF Reader (64-bit), system crash while loading Nitro_KissMetrics.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.
