DLL files are dynamic link libraries that contain code and data for various applications. Sometimes, you may need to register or re-register these files manually to fix errors or enable certain features. In this article, we will show you how to register DLL files in a Windows 10 64-bit system using the Regsvr32 tool.

What is Regsvr32 and How Does It Work?

Regsvr32 is a command-line utility that allows you to register and unregister DLL and .OCX files. It works by adding or removing registry entries for the specified files. You can use Regsvr32 to register DLL files that are not pre-installed on Windows, or that are not registered during the installation of an application. You can also use it to re-register DLL files that are corrupted or missing.

To use Regsvr32, you need to open the Command Prompt as an administrator and type the following syntax:

regsvr32 [/u] [/s] [/n] [/i[:cmdline]] dllname

Here are the meanings of the optional parameters:

• /u : Unregisters the file.
• /s : Runs the command silently, without any prompts or messages.
• /n : Does not call DllRegisterServer or DllUnregisterServer. This option must be used with /i.
• /i : Calls DllInstall or DllUninstall with an optional command line. This option must be used with /n.

The dllname parameter is the name of the DLL file that you want to register or unregister. You can specify the full path of the file, or use the current directory if the file is located there.

For example, to register a file named example.dll in the C:\Windows\System32 folder, you can type:

regsvr32 C:\Windows\System32\example.dll

Or, if you are already in the C:\Windows\System32 folder, you can type:

regsvr32 example.dll

After running the command, you should see a confirmation message that the file was registered or unregistered successfully. If you encounter any errors, you can check the troubleshooting guide from Microsoft.

How to Register DLL Files in a Windows 10 64-bit System

To register DLL files in a Windows 10 64-bit system, you need to follow the same steps as above, but with some differences. First, you need to make sure that the DLL file is compatible with your system architecture. Some DLL files are designed for 32-bit systems, and some are for 64-bit systems. You can check the compatibility of a DLL file by right-clicking on it and selecting Properties. Then, go to the Details tab and look for the File version or Product version fields. If the version number ends with x86, it means that the file is for 32-bit systems. If it ends with x64, it means that the file is for 64-bit systems.

Second, you need to use the correct version of Regsvr32 for your system architecture. There are two versions of Regsvr32 in a Windows 10 64-bit system: one for 32-bit files and one for 64-bit files. The 32-bit version is located in the C:\Windows\SysWOW64 folder, and the 64-bit version is located in the C:\Windows\System32 folder. You need to use the 32-bit version to register 32-bit files, and the 64-bit version to register 64-bit files.

For example, to register a 32-bit file named example.dll in the C:\Windows\SysWOW64 folder, you need to open the Command Prompt as an administrator and type:

C:\Windows\SysWOW64\regsvr32 C:\Windows\SysWOW64\example.dll

To register a 64-bit file named example.dll in the C:\Windows\System32 folder, you need to type:

C:\Windows\System32\regsvr32 C:\Windows\System32\example.dll

Note that you cannot register a 32-bit file with the 64-bit version of Regsvr32, or vice versa. If you try to do so, you will get an error message saying that the file was loaded but the entry point was not found, or that the file is not compatible with your system.

How to Register Multiple DLL Files at Once

If you need to register multiple DLL files at once, you can use a batch file to automate the process. A batch file is a text file that contains a series of commands that can be executed by the Command Prompt. To create a batch file, you need to open a text editor such as Notepad and type the commands that you want to run. Then, save the file with a .bat extension, such as register.bat.

For example, if you want to register all the .DLL files in the C:\Windows\System32 folder, you can create a batch file with the following content:

@echo off
for %%x in (C:\Windows\System32\*.dll) do regsvr32 /s %%x
echo All files registered successfully.
pause

The first line turns off the echo function, which prevents the commands from being displayed on the screen. The second line uses a for loop to iterate through all the DLL files in the specified folder and register them with the /s parameter, which runs the command silently. The third line displays a message that the process is completed. The fourth line pauses the execution and waits for a key press to close the window.

To run the batch file, you need to right-click on it and select Run as administrator. This will open the Command Prompt and execute the commands in the batch file. You should see a message that all files were registered successfully, and then press any key to exit.

Conclusion

Registering DLL files in a Windows 10 64-bit system is not a difficult task, but it requires some attention to the compatibility and location of the files and the Regsvr32 tool. By following the steps and tips in this article, you should be able to register DLL files manually and fix any errors or issues that may arise.
