The One-Click-demo installation install button doesn't exist

The One-Click-demo installation install button doesn't exist

Hi my name is Sergio Mendes Aguila and I am from Brazil. I installed the Axioma Template following the steps in the Help site. But the install button doesn’t exist in page (se the image ).

My WordPress is freshly installed, I upload the demo-data folders (plugins, themes, uploads), but I couldn’t found the Install Buttom.

I erased all the WordPress and install a new wordpress, I uploaded the demo-data folders again, and again the Install button doesn’t be there. Could you help me with this?

Thanks for while

Sergio Mendes Aguila
