After installing the Adobe Reader 10.1 on a WIN XP SP3 box and restoring the computer to an earlier time; the Adobe Reader 10.1 will not launch- see the program begin then just disappears, same thing when opening pdf file. Using add/remove programs - there are no Reader installations to remove. When I tried downloading the Adobe Reader 10.1 again from the Adobe website installation failed with this message; "The feature you are trying to use is on a network resource that is unavailable."
sorry Paul but welcome to world of Adobe. the software is a total piece of crap. I even went so far as to uninstall my security and it still won't download properly. it destroyed my older version and now I can't read a pdf at all.
