Problem activating pluggin theme wp blggn

I downloaded this wordpress theme (BLGGN : ) from envato element but when I have to install the plugins : ACF PRO, Theme option, Visual composer and WP instagram widget, it’s impossible to activate them.

The error message is: The archive could not be installed. PCLZIP_ERR_BAD_FORMAT (-10): Unable to find End of Central Dir Record signature

Could you help me solve this problem?

Thank you very much
