To automatically register DLL on the user's computer run regsvr32 your_dll_name.dll in the command prompt.
Or regsvr32 /s your_dll_name.dll (silent mode) form the installer.

There are also other ways to invoke automatic registration.
Just remember that auto-register function DllRegisterServer is built into your DLL.
