# Steam Wallpaper Download Issues

Keep in mind that all downloads are performed by Steam. Wallpaper Engine only shows the Steam download status, all download problems are related to issues with your Steam and not directly related to Wallpaper Engine. This guide contains a collection of the most common issues with downloads, in many cases the initial cause of problems are overzealous antivirus applications or blocked network ports.

If you are having issues with Steam downloads, make sure no antivirus application is blocking your Steam and that all necessary ports are open in your firewall - including any firewalls in your network routers.


You can easily check if your network router is blocking Steam downloads by switching to a mobile hotspot on your smartphone and attempt to download a wallpaper through that.

# Wallpaper download stuck at 0% or 100% (or any other percentage)

Steam is not done downloading and verifying the files. If the downloads are stuck for a while, try these things if your Steam downloads do not work even after you waited for a while:

  • Clear Steam's download cache in Steam's options:
  • Afterwards verify the files of Wallpaper Engine in Steam:
  • If all downloads are still stuck: Turn off Steam and afterwards delete the contents of this directory:
    • C:\Program Files (x86)\Steam\steamapps\workshop\downloads
      • If you have an anti-virus application installed, make sure that it's specifically excluding this directory
      • Note: C:\Program Files (x86)\Steam is the default Steam path, if you have installed it somewhere else, check there.
  • Restart Steam. Do not start any games. Check in the Steam download tab for progress and resume any paused downloads.
