I tried to open a PDF yesterday and found that Reader (v10) appears to have uninstalled itself (I have not uninstalled it since its last update and my flat mate states she has not touched any of my programmes). I downloaded the latest version from your website (v10.1.1) using firefox and found that when i tried to run the installation file, nothing happens. Task manager shows the process as running but it is not consuming any CPU use. I tried shutting down all other programmes and the same thing happens. I left the laptop for a while to see if it would run but it does not. I'm running windows vista.

Then, download the Reader installer from
and perform a clean install.
That seems to have sorted it. Thank you
