If it does not work for you, you likely have other issues as well as this. So far this method works in about 98% of cases.This is unlikely to affect other software on your PC.Has anyone seen this problem before? As it stands, the only way I know to get Reader X back is to do a full re-image of the machine. In case someone asks, I did perform all the above tasks in a user account with Administrator rights. I did also try to run Adobe's Cleaner tool to remove any lingering files but that didn't help at all. It almost appears that the installer started the update process overwriting the old program, failed the installation somewhere but did not roll back the installation and reinstall the previous version. The only remaining information I could find was a few reg entries and an empty folder in /Program Files called 'Adobe Reader DC' which was devoid of any files. What I then found was that the original installation of Reader X disappeared entirely and I couldn't reinstall any version! No listing for Adobe Reader X to be found in Programs and Features. The is was confusing enough since I was definitely updating from X (an older version) to DC (a newer version). I downloaded and ran the installer from the Adobe website and got a message that said 'The Installation process failed. My first thought of course was to simply update X to DC.

The version of Reader included in the image is Adobe Reader X. The user has a corporate webapp that is supposed to display reports in PDF form using Adobe Reader through an HTML frame.
