development environment

I am very new to this platform and am just trying to install the personal studio (as it is called in the tutorial).
I didn't get any of the prompts shown on the video (after registering), so I tried to download and install the development environment from the download section. I got a installation succesful message + note saying that the development platform will launch, but nothing happened.
Am I doing something absurd? How can I get connected to the platform?
Best regards,

Development Environment and Platform Server are for the server. Open Services and you'll have 5 services with names started with Outsystems. In the apps maybe it is easier to check for Configuration Tool, Start Services, Stop Services...

To develop you only need Servcie Studio (get it also from downloads section) and connect to your Personal Environment in the OutSystemsCloud or to you local server. To try is best to just use the cloud.
