Do make sure you the object selected (it will have a yellow bounding box around it) and hit the W, E, R keys on your keyboard to switch between Move, Rotate and Scale (Scale not available for characters).
It's also worth zooming out a little as the Gizmo may appear outside your view if you are zoomed in. For example, it will appear at a characters feet so you will not see it if you are zoomed in on the face.
Do also try loading a different character or prop like a 3D Block to check if the issue is only with that one object.
If you do still have problems, please post a full screenshot showing iClone open with the problem character/prop loaded.
