Ext_IO.dll for Lime Mini; Signal Generator

I can operate my Lime Mini SDR in receive using HDSDR, but when attempting to transmit, I receive error message that Ext_IO does not support Tx. The attached screen shots show which ext-io.dll is installed.

Is there an application that performs sweeping signal generator with Lime Mini ?

Help please !
