Startpage do not list PHP extensions

Question

Well, I have to work with service, that needs PHP 7.1.*

While installation, I got message, that two extensions (Intl and Curl) are not available:

Whenever, they are installed and uncommented in php.ini:

I've tried to use locations like:

"C:\Server\bin\PHP\ext\php_curl.dll"

Checked, that extension directory is true:

extension_dir = "C:/Server/bin/PHP/ext/"

Migrated from PHP 7.1.9 to 7.1.8, but nothing helps. Start page just displays error. Maybe someone knows what is the reason for such strange behavior?
