SSAS 2008: Class not registered REGDB_E_CLASSNOTREG

English This morning I was having problem with one of my VM. When I tried to access SSAS (SQL Server Analysis Services) and browse the cube - it throws error :  Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)) SSMS (SQL Server Management Studio) also open error message dialog box:  Exception of type ‘System.Windows.Forms.AxHost+InavlidActiveXStateException’ was thrown. Looking deep into detail error message, its clear that this function was called by Microsoft.
