How to Re-register and register DLL files on Windows 10
DLL files are library files. They help apps find the right libraries to use for whatever the app needs to do. The libraries themselves are often already installed on your system, and the DLL files just need to point the apps to them. Sometimes when you install an app, the DLL files don’t register or, during an update, the link between them and the app they belong to breaks.
The quickest way to fix this problem is to register or re-register the DLL files.
Register DLL files on Windows 10
Register all DLL files
Follow the steps below to re-register or register DLL files.
- Open Command Prompt with admin rights.
- Run the following command. This command will register DLL files that are located at the path in the command.
for %x in (c:\windows\system32\*.dll) do regsvr32 %x
- If you want to register or re-register any and all DLL files, regardless of where they are located on the Windows drive, run the following command with admin rights.
for %1 in (*.dll) do regsvr32 /s %1
Register single DLL file
If you have the name of the file you want to register, i.e., the one that’s giving you trouble, you can register just that one file alone.
- Open Command Prompt with admin rights.
- Run the following command and replace the path and name part with the actual path and name of the DLL file you want to re-register.
regsvr32 /u "path & filename of dll"
Other solutions
Registering a DLL file isn’t going to fix all problems with it. Sometimes, the DLL file isn’t the cause of the problem, it’s just how it manifests. The problem might be with the library itself or with the app. In that case, you should try uninstalling and reinstalling the app or removing and installing the library that it uses again.
It can also help to update the library if a newer version of it is available. Finally, check if the version of the library is the right one for the app. You can check the app’s requirements to see what libraries or frameworks are needed to run it.
