I can´t install theme on Localhost with WPMUDEV Dashboard

Hi !
I have a localhost with Ampps, and my site on upfront.detrezaweb.com (local domain).
I need install any theme with UpFront but when i can install on WPMUDEV Dashboard, the error it´s http://prntscr.com/bvxig9.
It´s possible install a theme with a file outside the dashboard ? I need download a file for install on localhost.
When i try install a plugins, it´s similar error.
Do you have any solution for work localhost with Dashboard?

I hope your request and thanks for all!
Thanks
