REGSVRr32 Tool - UnRegister DLLs =============================== You can use the Regsvr32 tool (Regsvr32.exe) to register and unregister object linking and embedding (OLE) controls such as dynamic-link library (DLL) or ActiveX Controls (OCX) files that are self-registerable. RegSvr32.exe has the following command-line options: Regsvr32 [/u] [/n] [/i[:cmdline]] dllname /u - Unregister server /i - Call DllInstall passing it an optional [cmdline]; when used with /u calls dll uninstall /n - do not call DllRegisterServer; this option must be used with /i When you use Regsvr32.exe, it attempts to load the component and call its DLLSelfRegister function. If this attempt is successful, Regsvr32.exe displays a dialog indicating success. If the attempt is unsuccessful, Regsvr32.exe returns an error message, which may include a Win32 error code. Example: To unregister Winshow's winshow.dll: Click the Start button, and select Run Enter this command line: regsvr32 /u [systemroot]\winshow.dll For example, in a Windows XP machine in which your systemroot was at c:\winnt, you would enter: regsvr32 /u c:\winnt\winshow.dll http://helpdesk.pestpatrol.com
