Following instructions in https://docs.moodle.org/33/en/Manual_install_on_Windows_7_with_Apache_and_MySQL, I install MySQL5.7(mysql-installer-web-community-5.7.19.0.msi), Apache2.4(httpd-2.4.27-win32-VC14.zip),PHP7.1(php-7.1.7-Win32-VC14-x86.zip),moodle3.3.1STABLE(https://github.com/moodle/moodle.git) on my desktop with windows 10 and chrome browser.
Every steps seems OK until step 7: install moodle. Error appeared(see attached png file), say curl need installed and enabled; opcache.enable setting should be changed, then I cannot proceed installation anymore.
I follows the links https://docs.moodle.org/33/en/admin/environment/php_extension/curl and https://docs.moodle.org/33/en/OPcache, but cannot fix the problem.
