How to Install DLL Files: Some Simple Techniques

Very often, for various kinds of software to work correctly, it may be necessary to download additional dynamic-link DLL libraries from the Internet, which themselves are not executable components, but are loaded into RAM during operation of the applications. Their absence can lead to serious errors. This applies to programs installed by the user himself and to system components. Every literate person should know how to install DLL files. As the most frequently used solutions, three main methods can be proposed, which will be further discussed in more detail.

Where to install the dll files?

To begin with, what is actually the so-called installation process. It includes two main stages: copying the dynamic library to a special location on the system disk and then registering the file so that the operating system can recognize it and perform further operations of loading into RAM or unloading from it at the end of a specific application. Please note immediately that not all libraries downloaded from the Internet need registration. Sometimes it’s enough just to copy them to the right place. But in what? It all depends on the bit depth of the installed operating system.

Directories for DLL Files

On Windows with 32-bit architecture, the System32 directory is used for this, and for 64-bit systems - SysWOW64 (both folders are located in the Windows root directory on drive C). To find the bit depth of the installed OS can be quite simple through the properties of the computer.

How to install a DLL file on Windows 7 or in any other version using the simplest method?

Now we proceed directly to the installation. To execute it, Windows provides a special system component regsvr32.exe - a program that installs DLL files by registering them. Incidentally, it can also be used for other types of objects with which problems arise associated with the appearance of system notifications that they are not registered in the system. But how to install DLL files on Windows? To do this, you can use the well-known menu to launch programs "Run". It simply prescribes a registration command indicating the name of the file with the extension. If this method does not work, and the system gives an error, after specifying the main tool, the full path to the file is entered.

Installation (registration) of the DLL file

For example, you have the msvcp110.dll library. in the first case, the registration command looks like this: "regsvr32.exe msvcp110.dll", in the second - "regsvr32.exe with: /Windows/System32/msvcp110.dll" for 32-bit systems or "regsvr32.exe with: / Windows / SysWOW64 / msvcp110.dll "for 64-bit systems. (all commands are entered without quotes).

Register on the command line

Speaking about how to install DLL files, another method can be used on Windows systems, which consists in using the same registration component, but launched through the command line. Actually, the result is the same.

DLL file registration via command line

The difference, as already understood, consists only in the fact that it is the command console that is called first (always with administrator rights), in which the same combinations are written, but with the full path indicated.

Opening a file through a program

Finally, if you look at how to install DLL files, you can even go roundabout.

Opening a DLL file

To perform the necessary operation, first through the PCM you need to call the context menu, select the item "Open with ...", and then through the browse button or search for programs on a computer, go to the System32 directory and specify the application regsvr32.exe.

Choosing a program to register a DLL file

Note: when using all three of the proposed options, at the end of the registration of dynamic libraries, a complete reboot of the computer is mandatory, since without it the system still does not recognize the registered object after the procedure.

Common Registration Errors

So, how to install the DLL files, figured out. Now a few words about the most common errors that may appear after executing commands. Most often, such situations are connected with the fact that libraries do not need to be registered or are already registered in the system, or downloaded files are broken, or they have absolutely nothing to do with dynamic components. The latter is associated with the penetration of viruses into the system, which can disguise themselves as system components. Also, original libraries downloaded from doubtful sources may already be infected with viruses, as a result of which an antivirus program, when trying to copy them to the hard disk or save them during the download process, can delete them without warning.

A few words in the end

It remains to give some practical advice on conducting registration processes. First of all, pay attention to the capacity of the system. The downloaded file must have the same bitness. Accordingly, place the files in the above locations. Otherwise, registering the result will not work. If performing an operation requires administrator privileges, agree without fail. If updates are provided for downloadable libraries, download the latest and most current version of the file. This will save you from the appearance of various kinds of conflicts between installed programs and their additionally installed components. Finally, if the files you’ve searched were still downloaded from a dubious resource, and copying them to the system partition, for example, from a USB flash drive, first check them for viruses using the standard antivirus commands built into the Explorer menu.
