I need to unregister MSCOMM control.

In windows/system directory,

regsvr32 mscomm32.ocx /u

displays that un-registering was succesfull and createobject( "mscommlib.MSComm" ) fail as expected.

However, if running a form containing this control, form runs witout errors and control works. After running form, createobject("mscommlib.MSComm") also works.

Why ? How to unregister control really ?
