Rundll32 errors can be a big headache for many PC users. However, they need not be. There are direct and simple solutions for your DLL error problems.

A DLL is part of a complicated file accessing system that allows programs to find the appropriate file it needs to run the proper processes. It is, essentially, a library of commands.

However, if a DLL file becomes corrupted, then it can cause a lot of problems (hang ups, freezes, etc.) for the average PC user.

I’m going to walk you through the three major causes of Rundll32 errors and demonstrate how you can fix them without calling an expensive computer technician.

Improperly Installed or Uninstalled Programs

If a program is interrupted or interfered with during its installation or uninstallation, then that might cause a rundll error. It is because a process is trying to access a missing or corrupt file from your DLL.

The best solution is to uninstall any recently installed programs. If you have recently uninstalled a program, then you should attempt to reinstall that program and then uninstall it again.

After these steps, reboot your computer and see if that fixes your rundll problems.

Viruses, Malware, Adware, and Spyware (Oh My!)

A virus is likely to pose as a DLL file because they like to be difficult and pretend to be important system files.

Check your “Processes” tab in your “Ctrl + Alt + Delete” window. If you see any rundll processes that are eating up a lot of system resources, then you have likely found your culprit.

Click “End Process” to temporarily stop the virus. Then, run an antivirus program to find and delete the nefarious program.

I actually suggest running the antispyware a few times. I have noticed that viruses like to shift and change (even if you delete them with your antivirus program). Sometimes the little buggers like to hide in different ways.

If you are in doubt if you have successfully deleted the virus, reboot your computer and run it again. If you are still having virus problems, then I suggest upgrading your antivirus software.

Clean Your Registry

Your registry can easily become corrupted by bits and fragments of old and unused programs.

A registry is a collection of information and settings for the hardware, software, users, and preferences. The PC continually references this data during its operation.

If your registry becomes “dirty”, then your PC will have problems correctly accessing the needed information from it. This is a common cause of rundll errors. Sort out corrupted and unused fragments such as rundll32 errors from your PC and needed files.
