Could not create a OLE DB Connection

I installed SQL Server 2012 SP1 on a Windows Server.
I was able to connect to SQL Server and Oracle ( after installing Oracle Client ) .

Then I installed I series Navigator in the server . After that , I cannot even create a new OLE DB connection in SSIS.
Getting the following error message .

I then uninstalled I Series Navigator .Still could not create a OLE DB  connection .

Thanks in advance for your help.

The new connection manager could not be created. (Microsoft Visual Studio)
