Regsvr32 failed to install/uninstall an ActiveX DLL.
When use regsvr32 /u "C:\Windows\System32\Macromed\Flash\Flash10a.o cx", it
says "DllUnregisterServer in Flash10a.ocx succeeded.", but the addon still
isn't uninstalled from IE7, which can be judged from the "Manager Add-Ons"
page - the Flash10a.ocx is still there.
Similar issue exists when use regsvr32 to register an ActiveX dll,
successfully registered but the DLL doesn't appear in the "Manager Add-Ons"
page, any ideas?

Edit: The OS Platform is Windows Server 2008 Enterprise, IE ESC is turned
off and security levels for all zones are set to default. The ActiveX can be
installed successfully if let IE7 download and install it.

Registering/unregistering a DLL or OCX has nothing to do with the add-ons
list in IE. It simply makes adjustments to the registry as required for
Windows to know where the DLL/OCX is located and it's GUID and classname, so
that should an application request a resource from that DLL/OCX it can do
so. The add-ons list in IE is controlled by a different registry key - to
remove items from it you can delete the appropriate entry, or simply use the
uninstall feature of the component. To add add-ons you should run the
install routine for that add-on rather than attempting to manually create
the registry value.
