How to Get Rid of Run.dll Errors

By Kefa Olang

Rundll.exe and Rundll32.exe files are command line utilities included in Windows operating systems to invoke functions of Dynamic Link Library (DLL) files. Rundll errors usually occur when Windows is unable to locate the file the utility tries to load. Most rundll errors are caused by malware programs such as spyware, Trojans and viruses. The errors affect software programs and cause start-up problems. With some simple troubleshooting guidelines, you can resolve rundll errors.

Step 1

Close all currently running programs and reboot your computer. Sometimes rebooting your computer will solve these errors. Move to the next step if it does not.

Step 2

Uninstall and reinstall the program that is running into rundll errors. To do that, click the Windows "Start" button and click the "Control Panel."

Step 3

Double-click "Add or Remove Programs" to open the programs window.

Step 4

Scroll through and click the program causing the rundll errors. Click "Change/Remove" to uninstall it from your computer. Reinstall the program using the installation disc or from the website if that's where you originally installed it from.

Step 5

Locate the error with the System Configuration Utility. To do that, click the Windows "Start" button and click "Run."

Step 6

Type "msconfig" (without quotes) and press "Enter" to open the System Configuration Utility.

Step 7

Choose "Selective Startup" and enable one of its components. Click "OK" to save the changes and restart your computer. If an error appears after restarting your computer, move to the next step.

Step 8

Run an antivirus program and remove all malicious files that could be causing the error. If you do not have an antivirus program, download a free one such as AVG (see Resources).

Step 9

Launch the antivirus program after it has installed. Perform a full system scan and delete all detected malicious files.
