Hi Scott,
Just to confirm, did you get any dialog asking you to provide the location of the installer msi or some particular file?
If yes, then please download the Reader 10.1.0 msi from here to you desktop and provide this msi path when the above mentioned dialog appears.
In case you don't see any such dialog, then how did you install Reader on you rmachine?
Did you install Reader from some network location or was it installed on your system by server admin?
thanks,
rohit
