Having trouble getting ground control to work

Hi I’m about to get my Maslow so im getting everything ready to go, so I go to trying to download ground control and extract the files so I can use it but I’m not getting anywhere and I don’t know what I’m missing. I’m downloading version 1.20 the windows portable version I go to my downloads I put it on my desktop then I right click and go to 7 zip extract files and I get nothing do I have to start at the beginning with version .61 and work my way up I would really appreciate any help I feel like an idiot for asking you guys because I know it’s right in front of my face I just am to blind right now I guess idk.

You don’t have to go back to .61.
If you think there is an issue with 1.20, try 1.18.
A far to detailed write up for win10 is here: https://docs.google.com/document/d/11Q5WBnmKBH_2bNahkFyXiZNlESf9TjCYlzXOWwsml-Q/edit?usp=sharing

Any anti virus notice?


Thanks for getting back to me so quickly. I will try 1.18 and no virus pop up
