No wp-config.php file how do I install the theme?

A wp-config.php file is not directly related to a WordPress theme. Not to sound too simple, but have you got your default WordPress blog setup already?

If so, here is more direction on getting a theme setup: https://codex.www.ads-software.com/Using_Themes

If not, here is how you can get your WordPress blog setup:

Hope this helps!

Thanks Anthony. Just back from the holidays and completely forgot how to set up a new WordPress blog. My memory kicked back in again after a few cups of tea :]

Thanks
