Regsvr32 is basically a command-line utility.
This command is used to register and unregister OLE controls for example the digital link library files and ActiveX controls in the Windows Registry. This command appears as the Regsvr32.exe file and is installed in the Microsoft Windows system file in the %systemroot%System32 folder.
The Regsvr32 command loads the library and tries to call the DllRegister Server and DllUnregister Server. In other words, it helps to register COM-based digital link library files to run different programs on your PC.
However, when the Regsvr32.exe file gets corrupt, you get the Regsvr32 to troubleshoot the error message on your computer screen. It can be displayed in various ways including the following:
“To register a module, you must provide a binary name.”
Generally, Regsvr32.exe becomes corrupt because either the load library, DllRegister Server or DllUnregister Server function fails. This indicates that the dll specified path was missing, incorrect, or couldn’t be found.
Here’s how the error messages are often displayed while registering a dll using Regsvr32.exe:
If this error message is displayed, it typically means that you entered an invalid combination of command-line arguments or switches when calling upon the Regsvr32.exe application.
The cause of this error message is that you called the Regsvr32.exe function with no modules to register located in the command line arguments.
You must re-run the Regsvr32 command from an elevated command prompt. For this, go to the start menu and type Command Prompt in the search box.
Now right-click the Command Prompt and click the option that says Run as Administrator to run the command on your PC. If it prompts you to enter an administrator password, type the password and then click Allow to run the command.
This may sound tricky but it is even simpler than the first solution discussed above. To register a 32-bit DLL using a 32-bit version of Regsvr32 on a 64-bit version of Windows, open an elevated command prompt.
After it’s opened, if you see the 32-bit DLL is located in the following path: %systemroot%System32 folder, move it to %systemroot%SysWoW64 folder. Once you change paths, run this command: %systemroot%SysWoW64regsvr32 <full path of the DLL>
Try following these 2 recommended solutions to immediately fix and repair this error on your computer.
The solutions should eliminate the occurrence of error messages such as “To register a module, you must provide a binary name.” It is so easy and effective and you can do it on your own without calling over a professional.
