Troubleshooting runDLL Errors in Windows 8

Reader Question: “Hi Wally, My computer is showing rundll errors, its a Windows 8 laptop. Please help!”  - Cameron W., United Kingdom

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: RunDll errors usually appear when the computer starts. The error is written in a way that it can be identified and fixed but most normal users don’t have a clue as to how these can be fixed. So lets dive in and find out how to troubleshoot runDll errors.

What are DLL files?

DLL files or Dynamic Link Library files are files that contain instructions, information, and functions for various programs. These files usually have a .dll file extension. Different DLL files do different things. Some come with Windows, others only come with certain software. RunDll belongs to Microsoft Windows and is used in RunDll32.exe to use different dll files stored in the computer. The RunDll32.exe process lives in \Windows\System32.

Cause of runDLL errors

Common causes for rundll errors are as follows:

  1. dll file has been moved or deleted and cannot be found where it should be.
  2. dll file is listed in System32 without being used by any application.
  3. A process is imitating rundll32.exe and causing problems.

Here are some common runDLL errors and their solutions:
