File extension .DLL

File description

The Dynamic-link library or the DLL file format has been developed by the Microsoft Corporation. The file extension is an implementation of the shared library concept in the OS/2 and Windows operating systems. Such libraries normally have file formats OCX and DLL or DRV. The DLL files are very much similar to the Windows .EXE files that are PE (Portable Executable for both 32 and 64 Bit Windows. The DLL files consist of data, codes and resources in different combinations.

Data files with similar files as the DLL, but with different formats possibly comprise of the resource sections, and are commonly called as the resource DLLs files.

Description of the problem

If you have on your computer a .DLL file that you cannot open, you are in exactly the same situation as thousands of other people who have similar problems with this or any other unknown file.

There may be several reasons why you cannot open the file with .DLL extension. Directly on this website you can find a solution of the most common problem with the .DLL file – that you do not have on your computer the appropriate program to open the file.

Solution

From the list below, select the appropriate program, install it and double click on the icon of a file that did not want to open - the problem with the .DLL file extension should be solved. However, if this does not happen, go back to the website to learn about other possible causes of the error, which have been described at the bottom of the website.

Other possible reasons why your .DLL file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .DLL file, there may be several reasons that cause problems with opening and operation of the data format:

1. Incorrect version of the installed application

A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .DLL file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .DLL file, so download the update and check again.

2. Incorrect .DLL file association with the program

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:

Right-click the .DLL file
Go to the "Open with" - then "Choose default program ..."
Locate the appropriate application
Click "OK"

3. The file is corrupt

It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
