What are NPInstal.dll Error Messages?


Dynamic Link Library NPInstal.dll Errors

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

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

  6. Restore your computer to that backup image.

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

Step 2: If recently installed Palm Desktop (or related software), uninstall then try reinstalling Palm Desktop 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 NPInstal.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 NPInstal.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.
