Currently clicking on a PDF (sample) in Internet Explorer 10 launches it in the standalone version of Reader XI.

Adobe removed the ability to control this behavior from Reader XI, and it has to be done at the browser level now.

I tried following this guide for IE8/9 and used the Enabled setting (sets the Adobe PDF Reader add-on to open PDFs in the browser), but the files are still launched outside of IE.

Do you want ALL PDF's to open in IE or just ones clicked on from within the browser? – Simkill Jan 17 '13 at 13:48
@Simkill Just the ones clicked on from within IE. I don't really WANT this behavior, I'm just trying to view this newspaper sample (click on the red button), but for some reason they require it opens in IE. If not I get some kind of dynamic error content within the PDF. – Louis Jan 17 '13 at 13:49
In theory it shouldn't matter if it's embedded in IE or not, it's still the same program viewing it. I get an error saying I need to install a different font package to be able to view that article from an embedded reader window. Maybe it's a similar problem? But then seeing as you want to view this in the first place would suggest you already have the correct character set installed. I'm still researching why the plug-in isn't opening it automatically for you. – Simkill Jan 17 '13 at 13:58
@Simkill sorry, I actually also got that message and had to install the Japanese character set. After doing so I get the dynamic error message. It pretty much says it will only display properly in the browser, and points to some instructions for an older version of Reader. – Louis Jan 17 '13 at 14:12
try a basic thing...remove adobe reader and its IE extension as well....reinstall it.. btw, what is the behavior in other browsers? – tumchaaditya Jan 17 '13 at 14:53
