The Regsvr32 tool is a command-line utility that can be used for registering and un-registering OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. If you find that some of your Windows functions are note working properly, you may need to register your dll files. This tutorial will tell you how to register or unregister a DLL file using the built-in Regsvr.exe or freeware Emsa Register DLL Tool.
Register dll file
To register a dll or ocx file, open a command prompt windows as an administrator, type the following and hit Enter:
regsvr32 “path & filename of dll or ocx“
Unregister dll file
To un-register a dll or ocx file, open a command prompt windows as an administrator, type the following and hit Enter:
regsvr32 /u “path & filename of dll or ocx“
This will register or unregister the dll file.
