want to install https://armania.kutethemes.net/home-12_2/ this demo but not showing option to install

Hi,
I have reinstalled the Organic 2 demo for you. The steps to install a demo as the homepage are as follows:
- First go to Settings / Reading and select the Homepage you want (screenshot_1).
- Next go to Pages / Select edit page that you just selected as the homepage in the step above (screenshot_2).
- Finally, when in edit page: you turn off the Enable Metabox Options option and copy the values ​​of the remaining options into Theme Options (screenshot_3, this is so that your entire website will have the same settings of the new homepage, Theme Options will be the place to store the main settings of the entire website).
Regards!
