It is important to put DLL files in the correct location in order for your applications to function properly. Here are the steps to follow to determine where to place your DLL files on Windows 10:
1. Determine if the DLL file is specific to an application or is a system file. If it’s specific to an application, then it should be placed in the same directory as the executable file for that application. If it’s a system file, it should be placed in the Windows system directory.
2. To find out where the system directory is located, open File Explorer and navigate to the Windows folder on the C drive. Typically, the system directory is located in the System32 folder. However, if you have a 64-bit version of Windows, there is also a SysWOW64 folder where some DLL files may be stored.
3. To put a DLL file in the system directory, you will need administrator privileges. Right-click on the DLL file and select "Copy." Then, navigate to the system directory and right-click inside the folder. Select "Paste." You will be prompted to confirm that you want to perform this action as an administrator.
4. If you are placing a DLL file in a specific application directory, simply copy the file to that directory and it should work with the application.
It’s worth noting that improperly placing DLL files in the wrong location may cause errors or even system crashes. Therefore, it’s always a good idea to back up any files before making changes to system directories.

How do I put DLL files on my computer?
DLL files, short for Dynamic Link Library files, are files that contain code and data that multiple programs can use at the same time. Adding DLL files to your computer is necessary especially if you are missing some essential files required to run an application properly.
Here are the steps to put DLL files on your computer:
1. Download the necessary DLL file from a trusted website source. Make sure to download the appropriate DLL file for your operating system and application requirements.
2. Next, locate the downloaded DLL file and extract it from the ZIP or RAR archive to your preferred location or directly to the system directory.
3. Locate the system directory by typing “C:\Windows\System32” (without quotes) in the Run window (Windows + R) or in File Explorer’s address bar.
4. Once you have reached the System32 folder, drag and drop the extracted DLL file into the directory.
5. A pop-up window may appear asking permission from an administrator account. Click yes, and the file will be copied to the system directory.
6. Close the window and restart your PC in order to let the changes take effect.
It is essential to exercise caution and ensure that the DLL files are obtained from a reputable source to avoid any risks of malware or viruses. In addition, be careful when making any changes to your system directory as it may cause problems with your operating system or applications.
How do I run a DLL file in Windows 10?
Running a DLL file in Windows 10 can be done in several ways. Here are some steps that you can follow:
1. Register the DLL file: You can use the command prompt to register the DLL file by opening Command Prompt as administrator and typing "regsvr32 /i DLLName.dll". Substitute the "DLLName.dll" with the name of the DLL file that you want to register.
2. Use Dependency Walker: Dependency Walker is a free tool for Windows that can help you to run DLL files. You can download it from the Internet and install it on your computer. Once installed, open the tool and navigate to the DLL file that you want to run. The tool will show you all the dependencies required to run the DLL file.
3. Use a third-party application: There are many third-party applications available on the Internet that can help you to run DLL files on your computer. Some popular applications are RegDllView, DLL Export Viewer, and DLL Injector.
It is important to note that running DLL files can be risky if they are not from a trusted source. Always make sure that you download DLL files from reputable sources and scan them with antivirus software before running them on your system.
How do I manually load a DLL in Windows?
Manually loading a DLL in Windows involves several steps, which are explained below:
1. Open the Command Prompt: Press the Windows key on your keyboard and type "cmd." Right-click on the Command Prompt and select "Run as Administrator."
2. Locate the DLL: Navigate to the directory where the DLL is located using the ‘cd’ command. For example, type "cd C:\path\to\dll" to navigate to the directory containing the DLL.
3. Register the DLL: Type "regsvr32 [dllname].dll" and press Enter. Replace [dllname] with the actual name of the DLL you want to load.
4. Verify the DLL is loaded: Type "tasklist /m [dllname]" and press Enter. This will display a list of tasks running on your system that use the specified DLL.
Alternatively, you can use the LoadLibrary function in your code to load a DLL at runtime. This involves linking to the DLL’s import library and calling the LoadLibrary function, followed by the GetProcAddress function to obtain the addresses of its exported functions.
What do I do with a DLL file?
DLL files, also known as Dynamic Link Libraries, are files that contain code and data that can be used by multiple programs, thus reducing the file size of individual programs and saving disk space. Here are some possible steps or reasons for what you can do with a DLL file:
1. Install it: DLL files are often installed as part of a software package or framework. You may need to install a DLL in order to run certain applications or perform certain tasks.
2. Replace it: If a DLL is missing or corrupt, you may need to replace it with a new one to get your program or system working properly. Make sure to obtain a reliable and compatible version of the DLL before replacing it.
3. Register it: Some DLLs need to be registered in order to be used by other programs. To register a DLL, use the "regsvr32" command in the Command Prompt.
4. Analyze it: You may want to analyze a DLL file to understand its functionality and dependencies. You can use tools such as Dependency Walker or Process Explorer to do this.
5. Develop with it: If you are a software developer, you can use DLL files to build your applications and share code between different projects. You can also create your own DLLs to provide functionality to other developers or users.
It’s worth noting that DLL files can be used for both good and bad purposes. Malware and viruses may use DLLs to execute malicious code or hide themselves from detection. Therefore, be careful when installing or handling DLL files and make sure to obtain them from trusted sources.
Where do I put 64-bit DLL?
If you’re working with a Windows operating system that uses a 64-bit processor, you’ll need to put your 64-bit DLL files in a specific location. Here are the steps to do so:
1. Navigate to the Windows\System32 folder (usually located in C:\Windows\System32\) on your computer’s hard drive.
2. Create a new folder within this directory and name it according to the name of your DLL file (without the .dll extension).
3. Move your 64-bit DLL file into the newly created folder.
4. Register the DLL file by opening a command prompt as an administrator, navigating to the folder, and typing the command "regsvr32 [dllfilename].dll" without the quotes.
5. Press Enter to execute the command, and your DLL file should now be registered.
It’s important to note that if you’re working with a 32-bit application, you’ll need to put your 32-bit DLL file in the Windows\SysWOW64 directory instead. Similarly, you’ll need to register the file using the command "regsvr32 [dllfilename].dll" in the same way as described above.
How does Windows find DLL?
Windows has a specific hierarchical file structure that it follows when looking for Dynamic Link Libraries (DLLs). Here are the steps that Windows uses to find a DLL:
1. First, Windows looks for the requested DLL in the application’s directory itself. If the DLL is present there, Windows immediately loads it.
2. If the DLL is not present in the application’s directory, Windows checks whether the DLL has already been loaded into the system’s memory. If the DLL is already loaded, Windows uses the loaded DLL instead of loading another copy.
3. If the DLL is neither present in the application’s directory nor already loaded, Windows searches for the DLL in the directories listed in the ‘PATH’ environment variable. The ‘PATH’ variable contains a list of directories where DLLs can be found.
4. As a last resort, if Windows cannot find the DLL in the application directory, already-loaded DLLs, or directories listed in the ‘PATH’ environment variable, it searches for the DLL in the default system directory for DLLs, which is typically the ‘%SystemRoot%\System32’ folder.
In summary, Windows follows a specific pattern of searching for DLLs which includes checking the application’s directory, loaded DLLs, ‘PATH’ environment variable directories, and default system directories.
