Simple Tool for Installing CHDK (STICK)
for Windows, OSX and Linux (Ubuntu)
The 'Download' Page
When a photo has been dropped, the STICK screen should look like this:
As you can see, STICK has identified the camera and Firmware information and is waiting for permission to download CHDK. Note that the build which STICK has selected was determined by which of the choice boxes was selected - here the Stable 1.2 version. The choices are now greyed out so it's not possible to change which build is to be downloaded (except by clicking the "Restart" button and returning to the startup screen). When you click the Download button, STICK will download the zip files from the appropriate CHDK site and unzip them. This process may take a minute or so, depending on the speed of your computer and internet connection.
When the software has been downloaded, STICK will display the next screen.
