Install Windows App activity The Install Windows App activity installs an application from an MSI package on a Windows target machine. Note: This activity replaces a Powershell activity by the same name available in releases prior to Geneva. If you have a workflow created in a previous version that uses the deprecated activity, your workflow will continue to work normally after upgrading to Geneva. However, all new workflows must use the custom version of this activity. This activity was built with the Powershell activity designer, which gives workflow administrators the ability to store input and output variables in the databus. Input variables Table 1. Install Windows App input variables Variable Description hostname Hostname or IP address of the target Windows machine on which the service is installed. Use the Resolve DNS MID Server capability to resolve hostnames into IP addresses. installerpath Path to the installer.
