# Install Digital End-User Experience

Install the Digital End-User Experience \(DEX\) application \(sn\_dex\) to start monitoring devices. Application and Device Health is included as a component of DEX.

## Before you begin

-   Review the [DEX Application & Device Health](https://store.servicenow.com/sn_appstore_store.do#!/store/application/0db59e3eade11d50f8777e45b2f98b72) application listing in the ServiceNow Store for information on dependencies, licensing or subscription requirements, and release compatibility.

## Procedure

1.  Navigate to **All** > **System Applications** > **All Available Applications** > **All**.

2.  Find the Digital End-User Experience application \[sn\_dex\] using the filter criteria and search bar.

    You can search for the application by its name or ID. If you can’t find the application, you might have to request it from the ServiceNow Store.

    In the list next to the **Install** button, the versions that are available to you are displayed.

3.  Select a version from the list and select **Install**.

    In the Review Installation Details dialog box, any dependencies installed with your application are listed.

4.  If you're prompted, follow the links to the ServiceNow Store to get any additional entitlements for dependencies.

5.  If demo data is available and you want to install it, select the **Load demo data** check box.

    Demo data are the sample records that describe application features for common use cases. Load the demo data when you first install the application on a development or test instance.

6.  Select **Install**.

    **Warning:** Digital End-User Experience is installed with mutual Transport Layer Security \(mTLS\) automatically enabled on the ServiceNow instance. As an updated, more secure version of SSL, mTLS enhances security by encrypting data and verifying the identity of both the client and server before establishing a connection. If you have legacy security products on any other integrations with ServiceNow, they might break after DEX installation. Update these products to support TLS or mTLS.
