please contact your purchased theme author, theme author will assist you.

How to contact an author to get support or for any technical query:


CURL ERROR 7 Failed to connect to Permission denied” error is caused, when for any reason curl request is blocked by some firewall or similar thing.

you will face this issue when ever the curl request is not with standard ports.

So, you can get a try with closing some software as like skype which is using port then try to install.
