It is working now. Here is what I did: Start Menu>type Start in console> right click and go to file location, then run the file "Start in console" as an administrator.

Hi and welcome,

This error seems to be a connectivity issue. Please ensure that you have correctly configure your network (Firewall, Forward or Rreverse Proxy) in order to install third-party apps.

See Configuring Marketplace connectivity article for further information.

Firewall Rules

To allow UPM to perform online functions behind a firewall, you need to set up firewall whitelist rules that enable UPM to connect on port 443 to these servers:

*.atlassian.com: UPM connects to several servers in the atlassian.com domain, including marketplace.atlassian.com, marketplace-cdn.atlassian.com, id.atlassian.com, maven.atlassian.com, and others.  

*.cloudfront.net: certain Marketplace assets (screenshots, logos etc) are hosted on cloudfront. Calls to that domain are expected.
