How to change a static IP address by CloudFlare?

I’m using Cloudflare WARP on Windows 10 Pro 64-bit. I need to change my IP to enable Kerish PC Doctor to update itself. How to do that?

Enable WARP, get IP from cloudflare

My IP is currently managed by Cloudflare:
Hostname: 104.28.214.144
ASN:13335
ISP: Cloudflare Inc.
Services: Network sharing device or proxy server
Assignment: Likely Static IP

What is more, I don’t know how to enable WARP.
In my Program Files, it is called Cloudflare WARP. When I clicked on it, nothing happened. There is no icon in the Task Bar (or hidden icons).

You already have it turned on

C:\Program Files\Cloudflare\Cloudflare WARP see this folder
