Looking into the registry is good, but here is an easier method: try to instantiate the OCX and trap the error. The error code should be 1733.

on error wait window str(error())
ox = createobject("t.t.1") && Use the ProgID as param

should display 1733 because there's no t.t.1 registered on my computer.
