Rundll32.exe errors typically occur in response to the inability of Windows to access an application, program or file as the result of a corrupted or missing DLL (Dynamic Link Library) file or in response to a rundll32.exe virus that has been designed to look like a normal Windows process.

Here are the easiest ways to fix rundll32.exe errors.
Click "Ctrl + Alt + Delete" on your computer's keyboard to open the Task Manager window.

Click the "Processes" tab and search for a rundll32.exe program.
If one is running and appears to be accessing a lot of your system's resources, click "End Process" as it is likely a malicious program and not a true Windows program.


Run software to seek out, detain and remove viruses, malware, spyware and adware. Often these malicious programs corrupt DLL files or cause them to be deleted or moved and, as mentioned, some rundll32.exe programs may in fact be viruses on your system.

Reboot your computer to update any changes you may have made recently to your files and programs.
Many programs and applications require a reboot for successful installation.

Uninstall a recently installed or changed program or application and then reinstall it using the default settings.

An installed program may not have loaded properly, an installation via the Internet may have been interrupted enough to create errors or the program may have a bug.

If you uninstalled a program and see a rundll32.exe error, reinstall the program and then uninstall once more.

Retain the services of a Microsoft certified technician, if all else fails, to review and fix your system's Registry.

The rundll32.exe process is responsible for running DLLs and placing its libraries in the memory. The rundll32.exe process is known as a command line utility program, and it performs its embedded functions along with the rundll.exe file. Rundll32.exe works by invoking a function that is exported from a specific 16-bit or 32-bit DLL module. However the only DLLs that you can call with the rundll.exe and rundll32.exe files are the ones that are only specified to be accessed by these processes.
The rundll32.exe file operates by parsing the command line. The specified DLL is then loaded through the function LoadLibrary(). Afterwards, from the function , it gets the addresses through GetProcAddress(). The command line tail is passed when the is called. Next, the DLL is unloaded upon the return of . Finally, the rundll32.exe file exits.We strongly recommend that you run a FREE registry scan to identify rundll32.exe related errors.

I am of the mind to do a complete reinstall of the operating system including flash the BIOS even if it is the same version. I worked many hours tracking down and thinking you found every part of the problem on to hit an .EXE and it all starts over again....I just clean out everything and start fresh.
If you tell us what make and model of computer along with the operating system it is we can direct you to the drivers for the reinstall. Some off those programs - for example AOL seem to be virus magnets. (if it is a dell it is really simple if you just put in your service code- it give you your particular driver of your computer.)
That is what I would do...Or you can keep hunting.
