At the moment this string reads "Pruebe a pulsar una vez, dos veces, desplazarse".

This message is quite confusing. To press, but where? Why twice? Moving around with my mouse? Why would I need this program for that?

I would propose the following translation:

"Prueba a hacer clic, doble clic o desplazarte usando la rueda del ratón."

But it seems like you are avoiding the "clic" term altogether, so the first part would feel a bit strange. In any case, please state the movement is done with the scroll wheel because it is not evident.
