Ever got yourself in a situation when your Windows 10 is asking you to register a .DLL file on your system? Well, Dynamic Link Library files are known as .DLL files. Multiple applications use the functions saved in a .DLL file to offer you certain features.
So, it’s important to register .DLL in Windows 10. Here we are going to discuss below- how to register, unregister, and re-register a .DLL file in Windows 10? Before we proceed with the methods, here are a few words regarding .DLL files. Once you know it, the registering process will be a cakewalk for you. Let’s learn it!
What Is .DLL File?
As we mentioned, .DLL files contain multiple functions to enhance your experience with an application. For instance, Microsoft Office uses the uncountable number of .DLL files. You can have certain functions like grammar checking, spell checking, etc., by enabling such files.
Even, you can use these files between different Office applications. Hence, whenever you get a DLL error on your PC, just register the .DLL file to fix it.
Why You Need To Register .DLL In Windows 10?
Microsoft Register Server is represented by a command-line tool-“regsvr32”. Windows users use this tool to register, unregister, or re-register the Object Linking and Embedding, aka OLE controls like ActiveX Control .OCX files and .DLL files.
When the command-line tool “regsvr32” registers a .DLL file, it adds the information of the corresponding program file to the Windows Registry. Thus, other programs can easily understand where the program data exists and how to interact with it.
However, now learn the process of unregistering and registering .OCX files in Windows 10.
How To Register A .DLL Or .OCX File?
If your Windows Registry lacks the required .DLL file reference or it has been damaged or corrupted; certain applications may stop working.
These applications can’t use corresponding .DLL file and land you up on a .DLL file error. Also, if the association of .DLL and Windows Registry file is broken somehow; you are going to face the error.
Generally, the .DLL files or .OCX files get registered when you uninstall and reinstall the program. However, there are times when you perhaps need to do it manually.
Here is the process of doing it on your own. Check it out.
Register 32-bit or 64-bit .DLL files in Windows 10
- Step 1: Firstly, click on your Start Menu and search for “Command Prompt” in the Cortana search bar
- Step 2: Now, click on “Command Prompt” and select “Run As Administrator” from the list
- Step 3: Your Command Prompt will be opened now with elevated properties
- Step 4: Next type, “regsvr32” followed by the path of yours .DLL file
‘regsvr32 “path & filename of dll or ocx”’
Now you must get a confirmation message conveying, your .DLL file got registered successfully.
In case, you get an error message instead of the confirmation message then check which version of the command you are using. If you are using 64-bit Windows version and your .DLL file is of 32-bit, then you have to run the command with a 32-bit version of the regsvr32:
“%systemroot%\SysWoW64\regsvr32 <PATH TO DLL>“
Unregister .DLL files In Windows 10
- Firstly, open your command prompt by performing Step 1 to Step 3
- Next, type in ‘regsvr32 /u “path & filename of dll or ocx”‘ and hit enter
- You have successfully unregistered .DLL file now.
Re-register .DLL files In Windows 10
- Open your Command Prompt first using the same steps
- Now type in ‘for %1 in (*.dll) do regsvr32 /s %1’
- Finally, hit the enter button and you are done with the process of re-registering yours .DLL file.
Note: When you are using a 32-bit .DLL file, ensure that you have moved the file from “%systemroot%\System32” folder to “%systemroot%\SysWoW64” folder beforehand. Else you may get stuck with regsvr32 error messages like-
- “The module failed to load“
- alternatively, “The specified module could not be found“
However, we have made our guide foolproof. So if you are facing such issues here, we are with the potential troubleshooting trick. Look below for the full scoop!
[Busted] Common regsvr32 Errors
We have rounded up a few frequently occurring regsvr32 errors and corresponding troubleshooting tricks. Have a look.
‘The module was loaded, but the call to DllRegisterServer failed with error code 0x80070005‘
When there is a conflict within given permission, you can see this error message. If you can’t register the .DLL file after using the command prompt then the file might have blocked itself.
You need to go to the “Security” section of that “General tab” in the .DLL file’s “Properties” window to check the issue.
‘The module failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files‘
If your PC has a missing dependency, then you might see this particular error. You can use the Dependency Walker tool to check the list of dependencies of that .DLL file. Once you find the missed one, add it to fix the error.
Perform all the steps accordingly and register yours.DLL file. If you face any issue in between the steps, drop a comment in the below box. We will reach you out within no time!
