You are not saying what you did so I really don't know if you did the above of not. It would be easier for us if you first told us what you did. For all I know you could have got the Indigo zip from somewhere on the net.
Sorry if my question was not clear enough. In fact, I had followed the tutorial you showed me without success. But I found the problem. It was on my side. In the Shield settings, under security I had to enable the 3rd party apps install authorizations on... It was only that.
Everything is working now. I like the new Indigo tool. With the config wizard, all the addons are installed automatically. Thanks and keep up the good work.
