how to register ActiveX DLL?

[r_shtykh]

I'd like to know how to register ActiveX DLL from a program or manually.
I need to register S2CM_TL.DLL in the registry with key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\S2CM_TL.DLL, and put also 2 names(EventMessageFile, TypesSupported) with values.

I've never done it before. Could you help me?
Thank you in advance.

Thank you, but I couldn't register it.
By the way, when I try to register it with regsvr32 I get "The DLL Server entry point was not found in S2CM_TL.dll". What can be the reason?

ive seen that prob with some winxp machines. Did it on files that reg'd fine on all other windows versions. I still havent found why. But sometimes that error comes from the DLL being edited perhaps with a resource editor and the PE header doesnt reflect the correct changes for byte offsets...
