When downloading adobe softwares, including adobe creative, my computer downloads the content slowly and then stop all of a sudden. The stopping in progress also happens when there's a disruption, like when the computer goes to sleep or I click of the window that the download was previously on. I've tried the how-to methods and part of the troubleshooting methods but nothing's working.
Make sure that you have all Windows updates that are available.
The one thing that was causing it for me, believe it or not, was that I needed to do a clean installation of the latest Studio graphics driver from the NVIDIA website. After doing that and restarting, all was OK.
