How To Register A DLL File On Windows

Are you wondering How to register a DLL file on Windows? keep reading as we will be tackling that question below.

Have you ever encountered a Windows problem where you need to register a DLL file on your computer? A DLL file, also called Dynamic Link Library, is a file containing functions used in several applications.

For example, Microsoft Office has hundreds of DLL files that can be used between different Office programs to perform certain functions, such as spell checking, etc. Several programs can load the same DLL at the same time.

Register 32 or 64-bit DLLs in Windows.

If you need to register a DLL due to some kind of corruption or installation failure, you can do it manually by following the method described below.

Step 1: First click Start, then Run.

Step 2: Now all you have to do to register a DLL file is to type the command regsvr32 followed by the path of the DLL file.

Step 3: Now click OK and you should get a confirmation message that the DLL was registered successfully.

That's it! Now your DLL has been successfully added to the registry and can be used by Windows programs. Note that if you get an error message, you may be using the 64-bit version of the command and not the 32-bit version. 

If a 64-bit version of Windows is installed and the DLL is 32-bit, you must run the command using the 32-bit version of regsvr32:

Also, if you are using a 32-bit DLL, be sure to move the file from the %systemroot%System32 folder to the %systemroot%SysWoW64 folder before running the command. Otherwise, you might see messages like:

If you are unable to register a DLL file and you get an error message that the attempt to register the DLL file failed, you may wish to disable UAC (User Account Control) in Windows.

Disabling UAC is known to solve the problem of failed attempts to register DLLs. Other issues may be that you have to right-click on the command prompt and choose Run as administrator. Sometimes, if the command prompt does not have administrator privileges, the register DLL command will fail.

Finally, if the regsvr32 command is missing or corrupted, you can run System File Checker to repair any issues with the original Windows system files. If you're still having trouble, post a comment! Enjoy!
