  • “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.\n\n Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.\n\n%2.”
