When you are done enter the Option Code manually in the DS1000z using a single string without using any 'dash' (-) using Rigol's Procedure for activating the Trial Options in the D1000z. As I recall the procedure is available on Rigol's Web Site under DS1000z.

I don't think it's available at Rigol's website.
But it's available at the North American distributor Rigol NA has documented the update procedure here:
Option license activation process for the DS1000Z, DS2000/A, DS4000, and DS6000 Oscilloscopes
Here are instructions for activating licenses for the DS1000Z, DS2000/A, DS4000, and DS6000 series of oscilloscopes.

I think you should update your guide to include the link for this document.

I had some difficulty finding the procedures on Rigol's web site for a DS1074Z can someone help? I could not find that specific model.

If you are still having trouble this should help you. It is for the DS1074Z and will give you 200 MHz BW, etc., and should get you going. If not please let me know. Cheers, Ted

Keyed in code for DSER key and all options are official! It now says Model DS1104Z instead of DS1074Z. Yes procedure was easy and straight forward :-+. Thanks Again. Haven't confirmed that I have 200MHz yet

No, its not possible on a DS1104Z or DS1074Z model :-(
linux-works:
sad to report, there is no new bandwidth in my 'upgrade'. I did an informal test before the upgrade using a tektronix sg503 signal generator. I started at 5mhz then went to 10, 25, 50, 100 and 250. just a bit beyond the 50 point (low 60's) the signal started to attenuate and was no longer flat. I'm not talking about 3db point, but the very first point where you can see the signal level drop as you increase freq.
the same basic point before the upgrade was there after the upgrade. I did not see any increase in where that falloff point came.
the good news is that the signal was easily viewable at 100mhz and even up thru 250mhz (my siggen's max limit). it was attenuated, sure, but very visible and clear (at least as a sine wave).
so, the decode features will unlock, but I'm not convinced any new speed exists with the unlock and its not really a different model number.

The model number changes from DS1074Z [70 MHz] to DS1104Z [100 MHz] with the upgrade.
