What are nossu2fn.dll Error Messages?

Dynamic Link Library nossu2fn.dll Errors

nossu2fn.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like nossu2fn.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. Nokia Software Updater) could share the same nossu2fn.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 nossu2fn.dll is attempted to be loaded either when Nokia Software Updater is starting up, or in some cases already running. Some of the most common nossu2fn.dll errors include:

Access Violation at address - nossu2fn.dll.
nossu2fn.dll could not be found.
Cannot find C:\Program Files (x86)\Nokia\Nokia Software Updater\nossu2fn.dll.
Cannot register nossu2fn.dll.
Cannot start Nokia Software Updater. A required component is missing: nossu2fn.dll. Please install Nokia Software Updater again.
Failed to load nossu2fn.dll.
The application has failed to start because nossu2fn.dll was not found.
The file nossu2fn.dll is missing or corrupt.
This application failed to start because nossu2fn.dll was not found. Re-installing the application may fix this problem.

Your nossu2fn.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Nokia Software Updater), or deleted by a malware infection. Furthermore, nossu2fn.dll file corruption could be caused from a power outage when loading Nokia Software Updater, system crash while loading nossu2fn.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 nossu2fn.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 nossu2fn.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.

In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the nossu2fn.dll error, please proceed to the Step 2 below.

Step 2: If recently installed Nokia Software Updater (or related software), uninstall then try reinstalling Nokia Software Updater 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 nossu2fn.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

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

If Windows Update failed to resolve the nossu2fn.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 nossu2fn.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 nossu2fn.dll file version. We maintain a comprehensive database of 100% malware-free nossu2fn.dll files for every applicable version of Nokia Software Updater.

Windows 10: C:\Program Files (x86)\Nokia\Nokia Suite\
Restart your computer.
