gibbon installer not launching

Hello every body,
I am testing gibbon 24 stable on my windows 10 laptop so I did the following

  1. Installed MAMP Free
  2. Installed Apache24
  3. Installed php 7.4
  4. Installed MySql 8.0
  5. downloaded gibbon bundle

my directory looks like this

what am I doing wrong

Hi Ashraf, when you say that the installer is “not launching” do you mean that you get a blank white screen? If so, and even if not, it is worth checking your PHP error logs to see if they can tell you anything. These are most likely in C:/MAMP/logs. Let us know what you find! Thanks, Ross.
