# Winget-Install ## Mods The Mod feature allows you to run an additional script when installing or upgrading an app. Just put the script with the App ID followed by the "-install" or "-upgrade" suffix to be considered. `AppID-install.ps1` and/or `AppID-upgrade.ps1` (if it differs, otherwise the "-install" mod will be used for upgrade) and put this in the Mods directory > Example: > If you want to run a script just after installing ".NET Desktop Runtime 6", call your script like this: > `Microsoft.dotnetRuntime.6-x64-install.ps1` In the case of ".NET Desktop Runtime 6" it spawns a new process and this we will have to wait for completion of before moving on to checking if the installation/upgrade suceeded or not. - (this seems to be handled in Winget Version: v1.3.0-preview)
