What are NapsterUI.dll Error Messages?


Dynamic Link Library NapsterUI.dll Errors

NapsterUI.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like NapsterUI.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Napster) could share the same NapsterUI.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 NapsterUI.dll is attempted to be loaded either when Napster is starting up, or in some cases already running. Some of the most common NapsterUI.dll errors include:

Your NapsterUI.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Napster), or deleted by a malware infection. Furthermore, NapsterUI.dll file corruption could be caused from a power outage when loading Napster, system crash while loading NapsterUI.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 NapsterUI.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 NapsterUI.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 NapsterUI.dll error, please proceed to the Step 2 below.

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

You can uninstall Napster software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button

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 NapsterUI.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 NapsterUI.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 NapsterUI.dll File (Caution: Advanced)

Download NapsterUI.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying NapsterUI.dll to your appropriate Windows system directory. Napster typically does not release Napster DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing NapsterUI.dll and all other DLL files for Napster. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
