That pointer leads me to a download of ADE 2.0.1 at http://www.adobe.com/uk/products/digital-editions/download.html
If I am not logged op, it doesn't seem to know I am in UK and works fine.
You need to get the website updated properly.
am trying to re install 1.7 it has all my books on but like you it goes round in circles i have downloaded version 2 but no books are on there x
In case you have trouble finding the ADE 1.7.2 installer, you can pick it from helpx.adobe.com/digital-editions/kb/cant-install-digital-editions/_jcr_content/main-pars/ procedure_2/proc_par/step_0/step_par/download/file.res/digitaleditions.exe .
But I will recommend you downloading ADE 3.0 (from the link mentioned in the reply 1.)
