How to register and unregister dll files
You can use the Regsvr32 tool (Regsvr32.exe) to register and unregister OLE controls such as DLL or ActiveX Controls (OCX) files that are self-registerable. This may be necessary to troubleshoot some issues with Windows, Microsoft Internet Explorer, or other programs.
RegSvr32.exe has the following command-line options:
syntax:- 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
/s – Silent; display no message boxes (added with Windows XP and Windows Vista)
To register a dll or ocx file :
Click Start >Type in Search Bar:
regsvr32 <path & filename of dll or ocx>
Click Enter.
for example:
