Linda, I am CCing this question and my (short) answer to the Ifeffit mailing list.

I am installing atoms for the first time on my Windows XP PC. When I download the file ifeffit.1.2.8.exe I can run the atoms command line version but I don't find how I can run the TK version on my PC. Thanks for your answer.
