An urgent question about how an ActiveX control used in a web page is registered in user's machine automatically

[znmaster]

I've made a ActiveX control, and I put it in a web page.
When users browser the page , the ActiveX control is downloaded,but not

registered in the computer automatically!! When you refresh the page,
the browser has to download it again!!
How can I solve this problem?
Should I solve this prolbem in the ActiveX control,or in the web page,
or in the inf file?
I've made a cab file including the .ocx,.dll, and .inf.
The .inf is like this:
[version]
; version signature (same for both NT and Win95) do not remove
signature="$CHICAGO$"
AdvancedINF=2.0

[Add.Code]
RTCDLL.dll=RTCDLL.dll £»RTCDLL.dll is a necessity in my .ocx
RTCActiceX.ocx=RTCActiceX.ocx £»My ActiveX control

; needed DLL
[RTCDLL.dll]
file-win32-x86=thiscab
FileVersion=4,2,4949,1001
DestDir=11
RegisterServer=yes

[RTCActiceX1.ocx]
file-win32-x86=thiscab
clsid={6F44DC44-CA89-4609-8368-67840CB76794}
FileVersion=1,0,0,1
RegisterServer=yes
; end of INF file

I need detailed instructions!!
Great thanks!!
