Why cant I open and view pdf files on the web. I am using Adobe Reader X and Windows Explorer.?
Have a look at your settings. Open up Reader>Preferences>Internet and you should have a tick in the box for "Display PDF in browser. It maybe the fix
Another suggestion is to check your internet option. With your Browser open click on tools>Internet Options>Pograms>Manage add-ons. Look at Toolbars and Extentions and make sure you have Adobe PDF listed
