Adobe's instructions for installing AIR in linux are lacking. Not all distributions will install with correct privileges from the .bin file that's downloaded from the Adobe web site.
To install in a more standard way, open a terminal and go to the directory where AdobeAIRInstaller.bin is located. Then at the command line type:
chmod -x AdobeAIRInstaller.bin
This will install Adobe AIR.
The install for the Photographer's Ephemeris didn't work if I checked or unchecked either of the options for adding a desktop shortcut or starting the program automatically after installation. It looks like they don't size the GUI install screen properly. At that screen, I just hit 'Enter' and the installation proceeded.
Adobe is still very clumsy and doesn't adhere to linux standards very well, but AIR and the Ephemeris did install for me, and appear to run properly. It would be nice to be able to type in lat and long directly, as I have a number of places that I could just type coordinates in faster than scrolling and zooming a google map.
There are several ways to get tide information with free programs in linux.
