Rundll Error Messages

Rundll error messages are often encountered when attempting to start a computer or to run a program loaded on the computer. The reason that these types of errors are encountered at these times is due to what the rundll files actually do. Rundll.exe and rundll32.exe are used to launch dll files stored on the computer. Rundll.exe and rundll32.exe are important parts of the Windows operating systems and are key to having other programs run properly.

Unfortunately, a number of viruses, malware and spyware applications have used the same filename, which is usually when errors begin to occur. Valid rundll files are located within the following folder: Windows\System32. If you find rundll files in any other places, it is likely that they are viruses.
Rundll errors occur because the program that is trying to be launched cannot access the appropriate files. In most cases, the error message will state that the program cannot be loaded due to a missing file.

There are several ways to correct rundll errors based on whether they are due to an error in the registry or whether through a virus infection. Listed below are a number of steps that can be followed so that the rundll error can be fixed.

• Restart your computer – In some cases, just restarting your computer will correct the problem. Usually, it is better to shut down and then start it again, instead of choosing restart. If this doesn’t help, you should move on to the following.
• Uninstall / re-install the program – As stated above, the error message often clearly states what program cannot be launched when a rundll error is encountered. Uninstall the program and try installing a new and up-to-date version. When you have uninstalled the program, be sure to delete and files or folders and then re-install the new version. Restart your computer after the installation completes and try running the program.
• Run an anti-virus scan – Using Windows Task Manager, you can check the directory for any file. By opening Task Manager and clicking on the Processes tab, you will be able to see all instances of rundll.exe / rundll32.exe that are currently running. You need to have the Command Line column present to see the path for the file. To view the Command Line column, go to View \ Select Columns and then tick the check box beside Command Line. If you see an instance of the file not found in the System32 folder, you should run a virus check to find and fix the virus.
