I just downloaded and installed openhantek_3.3.3-1_win_x64.zip but when I started it "Demo" mode showed all the markers, triger markers, etc etc but did not display any traces.
An earlier release (3.3.2.xx I think) worked OK - I also tried it with the real scope attached - it detected it OK as a DSO-6022BE but as before the traces are missing.

I'm running under Win7 64 Pro on a laptop.

Dave
