Smsc.exe How To Fix The RunDLL Error

The RunDLL error has been a big issue for many computers for over a decade now. It's a big problem with older computers and seems to be less common with the likes of Windows 7 & Windows Vista. Fortunately, there's a simple way to fix these errors.

What Is The RunDLL Error?

This error is caused by a file called "RunDLL". RunDLL is a file which calls other.dll files to help software programs perform different tasks. It's best described as being like a telephone switchboard - linking the function the program wants to do with the.dll file that it needs. The RunDLL file is used constantly to help your system run, but if you have any problems with it, then it will just show the Rundll error. This error is typically caused by certain dll files being unreadable or corrupted and is quite easy to fix.

How To Fix The RunDLL Error

Fixing this error is quite simple if you follow a basic method, which removes all possible problems that could cause it. Here's how to do it:

Step 1 - Reinstall any offending program

Many programs will cause the RunDLL error to appear as it will be unable to load the.dll files that it needs. If you keep seeing this error whilst opening / using a certain program, then you need to remove that program from your PC and reinstall it. This will put a series of fresh new files on your system which might cure the issue.

Step 2 - Clean out the registry

It's often the case that DLL files are mis-labeled or misplaced inside a part of Windows called the 'registry'. This is a database which stores information and settings about your computer, keeping it running as smoothly as possible. It also includes a series of "File / Path References" which tell your PC where certain.dll files are kept. It's often the case that these paths / settings become damaged or corrupted, making your computer unable to locate the.dll file it needs. To fix this, you need to scan through the registry with a registry cleaner. This is a program which will fix any errors that are inside the registry database, stopping the RunDLL error from loading up again.
