Users working with a computer based on the Windows operating system may encounter a RunDLL32.exe error. If you use earlier versions of the OS, those that were released before XP, then the error may concern the RunDLL.exe file. But few people know what this is and how the problem can be solved. But you need to deal with it, and the faster, the better, because otherwise the entire OS may fail.
What is RunDLL.exe and what is this program for?
Of course, you first need to figure out what the RunDLL.exe file is and why this program is so important for the operating system.
In fact, everything is simple. From the name of the program, you can understand that it serves to run dynamic libraries. They have a .dll extension and often look as shown in the images in the article.
To understand the full extent of the problem, it is also worth explaining what dynamic libraries are. So they are called because they can interact with several applications on the computer at once. And they are needed just for the applications to function. The DLL contains the code that is needed to correctly display any elements in the program or game (video effects, sound, control and other functions). That is, without the necessary DLL, the game or program simply will not start.
If you still do not understand what RunDLL.exe is, then here is an accessible explanation. The program presented serves to run the DLL. Starting the application, it compiles a list of dynamic libraries necessary for its functioning, this list is sent to the RunDLL.exe program, and already it starts all the DLLs from the provided list.
Now an understanding of what RunDLL.exe is, makes it possible to assess the degree of threat when an error occurs, because it is quite large.
Why the system gives an error with RunDLL.exe program
Understanding what RunDLL.exe is is one thing, and knowing the cause of an error associated with this program is another.
Although there are not so many reasons:
- The program has been moved from its directory.
- It is removed from the computer.
- It was damaged by viruses.
As mentioned earlier, the article will provide methods for fixing RunDLL.exe error, but they will not help in any way to solve infection problems. Therefore, before starting events, special preparations must be made.
Bug Fix: Preparation
If you have an error while starting RunDLL.exe, then first blame the viruses. In this case, before fixing it, do everything possible to eliminate the virus content that damages our program.
Of course, there is a way to check if he is to blame. To do this, go to the system drive (usually it has the letter "C"), then to the Windows folder and from there to System. This folder contains the RunDLL.exe program. Find her. The easiest way to do this is using search. If the file is not found, then most likely the virus moved it or the antivirus program quarantined it. But if it is there, then look at the size. It should be around 44 Kb. If the number is different, then the virus has made changes to the file code.
The well-known method of combating viruses is antivirus content. So run it and scan the entire hard drive with a deep scan. Of course, this can take quite a while, but it is better to play it safe.
Solution: use the file from the donor system
After you have verified that the virus has been removed from the computer, you can proceed to fix the error. There are several ways to fix it, but we will consider the most effective one - replacing the RunDLL.exe file.
It’s best to ask a friend to copy this file to a USB flash drive from his system and give it to you to move the file to his directory. We remind you that the path to it is as follows: C \ Windows \ System32.
If a friend is unable to help you, then this file can be downloaded, just be careful, since many spread viruses in this way. After downloading, check the file for their presence.
