Can't install FrameMarket

Hi! I tried to install framemarket according to the instructions provided but it didn’t work. I installed it at wp-content/themes and when I go to my Network admin > Themes, FrameMarket isn’t there to the network activation. I already try to move the gridmarket folder from the framemarket/themes folder and put it into the wp-content/themes folder, but nothing happens.

How do I fix it?

Thanks!
