Sometimes it happens that some programs in Windows environments do not start when the application executable is started, and the system displays a message stating that such a dynamic component (library) of the DLL format is missing or not registered. Next, we consider the question of how to register a DLL in the system in several ways, but only on condition that it is really available. The user will also draw attention to some possible errors that may appear when performing actions in any of the ways.
How to register DLL in Windows-systems by the simplest method?
Most software products designed for installation and use in Windows, in addition to the executable file of the program, contains many additional components. The DLL is one of those modules that, when the EXE file is started, is loaded into RAM, where the prescribed code is executed to them.
Moreover, the structure of the sequence of starting the program and loading the remaining components into RAM is such that almost all of them start from the same directory. Thus, in the simplest version, the question of how to register a DLL in Windows 10 or systems of rank lower is solved by placing the necessary files of this format in a directory with the main executable file of the program (EXE). But this is only suitable for those cases when the libraries themselves were absent, but then were downloaded separately, for example, from the Internet.
How to register a DLL in Windows XP and higher through the Run console?
Unfortunately, the above technique does not always work. Therefore, in Windows you need to use your own tools and tools. In particular, it all comes down to the use of the RegSvr software service, which is presented in the form of a regsvr32.exe file located in one of the system directories. On systems with 32-bit architecture, this component is located in the System32 folder, but in 64-bit modifications there can be two such files (the second component is located in the SysWOW64 folder).
Thus, before solving the problem of how to register the DLL in the system, it is necessary to find out what bit capacity the library itself is designed for. The further course of action will depend on this.
So, to register, you need to call the "Run" console (the easiest way to do this is through a combination of Win + R), in which you need to register the regsvr32.exe command, and after it, specify the full path to the library file after a space. In the case when registration with bit counts is required, to execute the regsvr32.exe file, you will also need to register the full path, indicating the location of the System32 or SysWOW64 folder.
Actions through the command line
A DLL can be registered in a similar way through the command line. It can be called from the Run menu through the abbreviation cmd (required with admin privileges).
Here, as in the case of the "Run" console, a command is written starting with the file name (regsvr32.exe), followed by the full path to the library file or with the full path at the beginning of the line for the registration tool.
Creation of registration through the "Explorer"
An equally simple solution to the problem of how to register a DLL in the system is to use Explorer or some other file manager.
Here you need to find the library file and right-click on it, and then select the line “Open with ...” in the context menu. Further in the list of programs for opening the DLL format it will not be presented, therefore, using the browse button, in the above directories you need to find the very regsvr32.exe file (depending on the length of the main program).
Possible problems during registration
Everything would be fine, but sometimes errors may occur. Most often, you can see a message stating that the so-called entry point DLLRegisterServer was not found.
The reason for this may be that the library is already registered, but is damaged. Perhaps the DLLRegisterServer module is not compatible with the current version of the system or the library does not support it, etc. You also need to remember that not all components of this type are designed for registration. If the file is downloaded from the Internet, it may very well be that the antivirus blocked it or completely deleted it during the download process.
Sometimes you do not need to use Windows tools to register. So for the D3D components that may be present in games, just install the updated version of DirectX, and for the MSVC libraries install Microsoft Visual Studio Redistributable. In extreme cases, if a pirated hacked copy of a software product was used, on the same Internet you should find the official version of the software and perform the necessary actions again (but just in this case such procedures may not be required). If the preference is given to an unofficial program, the download must be done with the antivirus and firewall disabled, but only on condition that the user is confident that the downloaded content is completely safe and does not pose any potential threats to the computer system.
