If you are saying that you have an EDU license for 26, but your machine will not run 26, then I am not sure if there is anything you can do except upgrade you machine.
I don't know if the EDU licence you have will work with older version (which you can freely download from the Graphisoft website).
Your best bet would be to contact edu@graphisoft.com and ask if there is an older version you can download.
Probably not because they only support the last 2 or 3 versions, and if your machine will not run 26, it probably won't run them either.
