I don't know; this may depend on your operating system, browser, and/or PDF Reader.
I use Windows, Firefox, and Adobe Reader X. When I click on the FP11 EULA link (in your post), it takes me directly to the English page.
There used to be a language selection bar on the left hand side for earlier FP versions; I don't know why this has been eliminated:
Thanks much for your fast and helpful reply. I'm a long-time Windows user that just made the switch to Lion on the Mac, so I'm still catching up. When I clicked (from the U.S. page) on the flash EULA links, all the downloads are each displayed in Arabic without the language selector bar (identical to the format of your first screen shot).
However, finally it dawned on me that although I would logically expect English to come up if I was on the U.S. page, the first language I could think of albhabetically was... Arabic. So I tried scrolling DOWN and sure enough -- alphabetical listing. Finally got the language selection bar in your second screen shot to appear. The English version started about page 86 to 105.
Appreciate the excellent description of the problem, cause and how to resolve it and the screen shots in the meantime. Also your patience, as I am certain this is a frequent issue!
There really should be a language selection bar, as it was there for earlier releases.
I will write a feature request that this will be re-implemented.
