# Select wallpapers per application
Wallpaper Engine allows you to automatically launch different wallpapers whenever a certain .exe is launched on your system. For example, this may be useful if you want to have less distracting wallpapers whenever playing a game or automatically launch an audio visualizer when starting your music player.
If you are having technical problems with certain games or applications, you can also use application rules to disable Wallpaper Engine when a certain .exe is launched. If you want to solve a technical problem with another app, view this guide instead: Fix issues with specific apps or games
# Setting up an application rule
In the Performance tab of the Wallpaper Engine settings, click on the Edit button in the Application rules section. Click on Create new rule to set up a new set of wallpapers for an .exe of your choice. In the Application name input field, enter the name of your .exe, make sure the name matches exactly, for example musicplayer.exe. Set the Condition to Is running. In the Wallpaper playback option you can select one of the following options:
- Load wallpaper
- Load playlist
- Load profile
What is important to note here is that Load wallpaper and Load playlist will both only load one wallpaper and span it across all screens. If you have multiple monitors and want to load independent wallpapers for each screen (or even different playlists on each screen), you need to use the Load Profile option. Read the following section for more infos on how to set this up.
# Setting up a multi-monitor profile
Load Profile in the application rules refers to mulit-monitor profiles which can be configured in the monitor overview (screen icon in the upper right corner of the interface). A profile is a snapshot of all your currently selected wallpapers and playlists across all your screens. Whenever a profile is loaded, all wallpapers and playlists will be placed according to the profile configuration.
Configure your wallpapers and playlists across all monitors the the way you want them to be, then click on the Save profile button in the monitor settings and save the current setup under a name of your choice. Keep in mind that any subsequent changes you make to your setup will not change the profile until you use the Save profile button again. You can set up multiple profiles and assign them to multiple apps at once. For example, you may create a Music, a Gaming and a Movies profile and then assign each profile to all .exe files that match these categories.
