OVERVIEW OF THE ERROR

Rundll32 is a type of Windows Utility that is responsible for running and loading the 32-bit DLL or Dynamic Link Library number of files. These contain program code and important data that are accessed by multiply Windows programs simultaneously. Rundll32 needs to be healthy and working properly all the time for Windows programs to open correctly. However, if this is lost or corrupted, the program would fail to launch and the user receives the error prompt.

It is hard to pinpoint the exact reason for this error, but it may be a result of one or few events that affect the system. For one, it could be that the RunDLL32 is corrupted and needs to be fixed before the program could run again. This error may also be caused by a problematic program that is calling the DLL; it could either be corrupted or under a malware threat. It could also be that the malware is directly infecting the utility by posing as a valid Windows event. You can run an antivirus software or download one if you do not have it yet, and run a scan to check for any malware that may be causing your system to fail.

There are also instances wherein the antivirus software is the one causing the error. Some antivirus programs interfere with system execution of tasks. You can try uninstalling the program or disabling its services and then check whether the problem still persists.

HOW TO FIX THE ERROR

You can uninstall newly installed programs to check whether these are the ones causing the error. You may also try these other methods and see if any of them resolves the issue on your computer.

The Nero software may be causing the error, so you can try uninstalling or updating to newer version to solve the problem. Nero is a preinstalled software in Windows, and it is updated regularly. However, if some unwanted events like power failure of improper installation happens, Nero might cause the Rundll32 error. Renaming the files accessed by the program or uninstalling them completely is a step to take to ensure that the rundll32 error does not affect the computer anymore.

C:\Program Files\Common Files\Ahead\DSFilter

Method 2: Renaming or re-registering Impgvd.ax

If the Nero software is not on your computer, other software might be causing the problem, such as the Intel Viiv Software. You can try re-registering or renaming the files that are used by the program and see whether this is the cause of the error. If it is, renaming should solve the problem.

1. Press Win + E and locate C:\Windows\System32 and locate the Imgspl.ax file.
