I am trying to download adobe photoshop from the Creative Cloud, however it keeps getting to 8% and the failing. I have tried uninstalling and installing Creative Cloud, but to no avail. I can install lightroom just fine so it does not seem to be a firewall issue or similar.
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.
