If you are using an antivirus application, please make sure to configure it so that it ignores the wallpaper_engine installation directory and all important Wallpaper Engine executables:
If you have an anti-virus application installed (except Windows Defender), it's very likely that this is the cause of your problems. Take some time to investigate this further if your first attempts do not fix this issue.

Wallpaper Engine works well with most desktop-modification applications. However, some applications such as StarDock DeskScapes also modify the Windows wallpaper and it is not possible to run both applications at the same time. If you use a similar application to Wallpaper Engine, you will need to decide on one which you want to continue to use.
Generally, Wallpaper Engine works fine with Fences. However, if you have Fences installed but have disabled it, it will hide the wallpaper from Wallpaper Engine. You need to either enable or uninstall it completely.
