You can download the files for this theme from my Github account.
Installation is easy, just be very careful that you have backed up your site files before you do anything. Download the files, unzip and then place the columnerdeux folder in the /ndxzsite/ folder and put all of the affiliated files into their respective folders.
Then, select columnerdeux inside your Indexhibit studio at Admin > Themes.
You are installed! Now, you can customize as you wish.
