What is Regsvr32 Error? - What Is It?
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.”
Error Causes
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:
- “The command-flag "%1" is not valid. Please review the command usage and try again.”
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.
- “To register a module, you must provide a binary name.”
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.
- “The module "%1" failed to load.nn Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.nn%2.”
