I don't think Acrobat 9 supports touch screen. Acrobat XI does. I am not so sure about Acrobat X, perhaps not.
Consider - Touch screen requires a contemporary OS. The Acrobat 9.x product family is not coded for and so not compatible for the contemporary OSs.
The Acrobat 9.x product family passed into "End of Support" mid-year of 2013. There'll be no updates eh.
If you are working in a contemporary OS you'll need to move up to Acrobat XI.
