# Install multiple applications

The Install multiple applications step will install a list of applications in the order that they are specified.  This list of applications can be configured on the step itself:

Multiple applications can also be installed using a task sequence variable. You can specify the prefix for that list with a default of "Applications":

This list can be set via a Run PowerShell script step or a web service call.  An example PowerShell script that specifies the content IDs and versions of four applications that should be installed:

```powershell
# Install my list of apps
$tsenvlist:Applications = @("d7775b33-9cfe-4fcd-b3a2-dc129cfc769e:1", 
  "c2032a9a-d15a-4275-97a2-e317a84f3437:1",
  "2ae9d965-e89f-4e10-89e1-e55caeda997b:1", 
  "ebe17300-286a-4bf2-a172-aa8a4d64b186:1")
```
