Recently Adobe started providing the self-destructive executable of the web installers for both these softwares.It means once you download the small web installer exe file and double click it,the installer will start downloading the software for you but the tiny exe will disappear automatically.Now if you frequently reinstall your Windows or for any of your friend ( Like I keep on reinstalling Windows either on one of my test computers or my friends computer who leave thier laptop to get it fixed),its a wastage of time going to the site and downloading the web installers every now and then moreover they get disappeared as well.So if you get any error while downloading once you initiated the web installer you need to repeat the procedure.Really frustrating isnt it?
