Got Klok working on Ubuntu 14.04 LTS.

I used the free WineHQ software which enables many Windows applications to run on Ubuntu.

Steps:

1) Installing WINE, part 1 of 2: I ensured a pre-requisite package was installed
https://www.winehq.org/download/ubuntu

2) Installing WINE, part 2 of 2: I then installed WineHQ from the commandline, issued command:
sudo apt-get build-dep wine1.6

3) Installing Adobe AIR – part 1 of 2: I downloaded Adobe Air from here
http://labs.adobe.com/downloads/air.html

4) Installing Adobe AIR – part 2 of 2: I right clicked on the downloaded air16_win.exe file, from: http://labs.adobe.com/downloads/air.html
From the pop-up menu, I selected Open With, then selected Wine Windows Program Manager and followed the steps from there.

5) Then I downloaded Klok from the ‘Download Now’ link on http://getklok.com/features.html#versions

6) I right clicked on the download Klok2.air file and from the pop up menu, selected Open With Adobe AIR application installer. And followed the Klok installation instructions as per usual.
