Class not registered Exception from HRESULT: 0x80040154

when I run the application it always returns the following error

System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {998B125A-4959-4A18-A805-CC5500DF0A71} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

I am working with a WinForms application with framework 3.5, and I compile in x86, since my OS is Win 7 32 bit

I have registered the libraries as follows:

regasm c:\code\Interop.SecurityProvider.dll
