I installed the drupal8 rc1 version on server and getting the opcache enable issue. It is asking to enable the opcache first to proceed the installation . I figured it and solved it as :

Go to PHP configuration / php.ini file and add these two lines end of the page

[opcache]
zend_extension=php_opcache.dll
; Determines if Zend OPCache is enabled
opcache.enable=1

You can also increase the max execution time on php.ini configuration file. Default from 30 to 180.
max_execution_time=180

Hope it helps to install the drupal8 rc1 version on xampp or wampserver.

I take it, you must be running PHP 5.4 or higher?

Here I created video for how to solve this problem when installing Drupal 8 on XAMPP

https://www.youtube.com/watch?v=6SAHCzzk8B8

So as when installing Drupal 8 I just skipped this problem and fixed all problems (Trusted host settings, Opcache etc) after as I show in my videos

Hope this helps
