What Is A DLL File?

A DLL, or Dynamic Link Library, is a collection of small executable files or functions. They canbeused to perform a number of tasks in the same way that any executable file is used to perform tasks. However, the functions and features that a DLL offers is much more restricted. There are also a number of other distinct differences between a DLL and an EXE file that we cover later in the guide. For now, though, it is important to realize that while a DLL is essentially an executable file, it cannot be run independently.

The Windows Registry And DLL Files

The Windows Registry is one of the most important facets of the Windows operating system. It includes all details, settings, and information regarding your system, the users on that system, and the software installed. New entries are added to coincide with the addition of a new application or even a new file. The registry should also update when an application is removed by similarly removing the entries associated with that application, unless they are still required by another program.

Every DLL and application on your computer requires at least one registry entry in order to store pertinent details about it. When a new DLL is installed, a new entry should be added. When an old DLL is removed, Windows should first check to see whether it is required by any other applications and then remove or update the entry as appropriate. If a DLL is updated or changed in any way, then, again, the associated registry entry should also be changed to represent the differences.

DLL Problems and Dll Error types

As well as incorrect, duplicate, or missing registry entries there are many other problems that may befall the DLLs on your system. It is possible to recover from virtually any error, but it may require some work, and may also mean a loss of functions in some programs. One of the leading causes of problems is an incorrect DLL version being called, and this can occur frequently. It may require the installation of several versions of a DLL, although most are backwards compatible.

General Steps To Fix DLL Errors

While most DLL errors are unique there are some steps that you should attempt before attempting to search for and reinstall the DLL you need from the Internet. Not all websites are trustworthy and, as such, you run the very real risk of potentially installing a virus or spyware riddled DLL onto your system. In most cases you should be safe, but if you can avoid taking the risk then you will avoid the possibility altogether.

Close down all open applications after saving your existing work. Attempt to open the applications again, and calling the same features as you did when the problem manifested itself. This provides your system and the software with the opportunity to open properly and can genuinely improve your chances of a trouble free session.

The switch off and switch on technique has long been the butt of many an IT joke. However, it does help to resolve a lot of problems because it gives your system the opportunity to reopen necessary files, including the DLLs required by your system and the software you are running on it. Always restart your computer properly, whenever possible.

Replacing A Missing DLL

With many DLL errors, you will have to do your research to discover the exact reasons behind the error. A good place to start this research is the Microsoft knowledge base website. The knowledge base contains literally thousands of articles, many of them related to DLL errors providing the reasons, the symptoms of the error, and the advised resolution. Where a Windows update has been released to assist in the resolution, a link is also usually provided to make your life easier.

Registry Cleaning

We've already discussed the importance of the Windows registry. It contains all of the relevant settings for your computer, the software installed on your computer, and the various users that log on to your computer. When you first start your computer, the Windows operating system consults the registry to determine the applications that should run on startup. When you open a file or an application, Windows consults the registry to determine the settings you use. When you perform virtually any task within Windows or a Windows based application, the changes are stored within the registry.

With regards to the use and handling of dll files, the registry contains information regarding each of the dynamic link libraries on your computer. If an application attempts to call a dll file then it will first query the registry to determine any relevant information that it requires. As such, the registry is highly important to the ongoing use of your dll files as well as your system and software as a whole.

Common DLL Errors

A lot of DLL errors are very specific to what you are doing when the error occurs. This is because a DLL can contain such a large number of different functions, of which you probably only require one or a small number at a time. When attempting to deal with a DLL error you should record as much information as possible. You should attempt to regenerate the error in order to help determine the exact reason.

In a bid to help you research any problems you might be suffering with DLL files we have included a list of some of the most common errors below. There are approximately 30 errors, and while this may only touch on the surface of the potential problems, they are a varied range of errors so give good insight into how you may be able to tackle similar errors on your own computer.
