What are npptools.dll Error Messages?


Dynamic Link Library npptools.dll Errors

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

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



How to Fix npptools.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your npptools.dll issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the npptools.dll error, please proceed to the Step 2 below.

Step 2: If recently installed Easy WiFi Radar (or related software), uninstall then try reinstalling Easy WiFi Radar software.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many npptools.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the npptools.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your npptools.dll File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate npptools.dll file version. We maintain a comprehensive database of 100% malware-free npptools.dll files for every applicable version of Easy WiFi Radar. Please follow the steps below to download and properly replace you file:

  1. Locate your Windows operating system version in the list of below "Download npptools.dll Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate Easy WiFi Radar folder location:
    Windows XP: C:\WINDOWS\system32\dllcache\
    Windows XP: C:\Windows\System32\
    Windows 10: C:\Program Files (x86)\Makayama Interactive\Easy WiFi Radar\
    Windows 10: C:\Program Files (x86)\WM Converter\
  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve npptools.dll problems.

Makayama Media typically does not release Easy WiFi Radar DLL files for download because they are bundled together inside of a software installer.
