In Acrobat Reader preferences (writing on OS X here), choose 'internet' from the sidebar. there is a box labeled "display pdf in browser using...". Click on it to uncheck it, to prevent pdf's loading in browser.

Wouldn't that change the setting for your own machine, rather than the end-user's machine?

The better solution here, seems to me, is to force the file to download with a 'save this file' dialog (using a mime-type setting? I can't remember).

best, a.
