+#### Downloading ARC without using the app store
+
+If an IT environment prevents the use of the Windows Store app or limits access to the retail store, IT administrators can make this app available through other ‘offline’ deployment paths. 
+
+This deployment path can be enabled with the following steps:

+1.	Go to **Manage – Settings**, and turn on **Show offline apps** under **Shopping experience** as described at https://businessstore.microsoft.com/en-us/manage/settings/shop 
+1.	Go to **shop for my group** and search for the [Advanced Recovery Companion](https://businessstore.microsoft.com/store/details/advanced-recovery-companion/9P74Z35SFRS8) app.
+1.	Change the **License Type** box to offline and click **Manage**.
+1.	Under Download the package for offline use click the second blue **“Download”** button . Ensure the file extension is .appxbundle.
+1.	At this stage, if the Desktop PC has Internet access, simply double click and install. 
+1.	The IT administrator can also distribute this app through System Center Configuration Manager (SCCM) or Intune.
+1.	If the target PC has no Internet connectivity, some additional steps are needed: 
+    1.	Select the unencoded license and click **“Generate license”** and under **“Required Frameworks”** click **“Download.”** 
+    1.	PCs without internet access will need to use DISM to apply the package with the dependency and license. In an administrator command prompt, type:
