The software is available on the lrp website. It is kind of hiding inside the firmware download zip file.

It is also available on petitrc.com in the setup sheets section.

I updated my flow WT to 3.8. getting it to connect was a nightmare!
I tried a super spin and it connect seemlesly. I broke out s brand new flow comp. and the same connection errors.
Luckily I figured out how to do it...
You need to connect the computer (I used a mac,el capitan I think).
Open the app. before you click on connect you need to hold down the "SET" button on the Flow. Then click on connect while holding down "Set"
whether you have the on/off switch on is indifferent. (I tried)
Once you the firmware has been flashed you need to do a factory reset.
With you radio on hold down "set" and plug in battery. Hold for 3 seconds after turning speedo on.
You then need to re calibrate to your radio, and make any other adjustments...
Like everything, its easy when you know how
Good luck. : D
