Visit this link -
Specify your OS and language and click Continue.
On next screen select radio button for Adobe Reader 9.3 and click 'Download Now'
Wait for few seconds and DLM will start downloading and installing the Reader 9.3 automatically. (Take care of the gold bar at the top of the browser window - as mentioned on the site page)
NOTE: On the final screen you will see text like this-
Thank you. Your download will start automatically.
If it does not start, click here to download.
Do not click on 'click here to download link' as this will just download the Reader installer only. DLM doesn't comes into picture if this is done.
