Google has announced that it will end support for Chrome Apps for ChromeOS. You can find more details from Google at End of support for Chrome apps. As a result, the ScreenCloud ChromeOS Player must now run as an Isolated Web App (IWA). This guide will walk you through migrating from the ScreenCloud ChromeOS player legacy Chrome App version to the new IWA version to ensure your digital signage continues running smoothly.
Before you begin
Requirements
ChromeOS version 140 or later is required to run the ScreenCloud ChromeOS IWA Player — devices on earlier versions are not supported. This is due to the fact that Isolated Web Apps (IWA) and the Controlled Frame API are only available from ChromeOS 140 onwards
The ChromeOS ScreenCloud player must be active and online. Screens that are offline, suspended, or deactivated will experience issue migrating.
Recommendation
Migrate your ScreenCloud ChromeOS player from the Chrome App to the IWA before July 2026.
Important
After installing the new IWA player, do not delete the existing Chrome App Player if you experience any issues. Contact Support first so the issue can be reviewed and resolved before removing the Chrome App Player.
Step 1: Install the IWA ScreenCloud ChromeOS Player
In Google Workspace Admin
Select your Organization Unit
At the below right corner, hit the + button, then hit the box icon Add an Isolated Web App
Fill in the Web Bundle ID and Update Manifest URL values from below then hit SAVE
Web Bundle ID:xg7j4jhurxb7v5kpnt6asdfdap4lgygu7rxw6wwmpg4p3zs3rffaaaic
Update Manifest URL:https://chrome-iwa.screencloud.com
Click your installed app to toggle more settings, make sure Web app can run offline is enabled.
Then scroll down to Extensions section then hit Add Extension > Add from a custom URL
Fill in Extension ID and URL from below.

URL: https://chrome-enterprise-extension.screencloud.com
Hit Save at the above right corner.
Set Auto-launch app to the name of the installed player (
https://chrome-iwa.screencloud.comin the image sample below), then hit Save again at the top right corner.
Step 2: Reboot ChromeOS devices
Go to ChromeOS > Device
Select the Organizational Unit (OU) that contains the ChromeOS devices running the Legacy Chrome Player.
Select all devices, then choose the Reboot option from the dropdown menu.
The selected devices will reboot and automatically launch the new ScreenCloud ChromeOS Player (IWA) version. The same content that was playing on the legacy version should now be playing on the new player version.
If the devices still boots into the old Chrome web app player for the Auto-launch app, please wait for a few minutes and try again.
Step 3: Remove the Chrome app version after installing the IWA Player
Remove the Legacy Chrome Player only after you confirm the new IWA player is set as the Auto-launch app for the kiosk settings of your ChromeOS device(s), as seen in the image below.
Once this is confirmed, follow the steps below to remove the old player version:
Go to Menu > Devices > Chrome > Apps & extensions > Kiosks.
In the Kiosks app panel, select the Legacy Chrome Player with the app ID

Select the trash icon, and confirm removing the app
'Device Already Associated' error
The cause of this error
Duplicate migration attempts – the same device is being migrated more than once, which is blocked for security reasons.
Uncleared migration state – the previous app's migration state has not been fully cleared, so the device is still flagged as already associated.
This error requires a support agent to fix it manually
There is no self-service step that will clear it, so please contact ScreenCloud support once you've checked the points below. The following helps confirm what happened before the error appeared and prevents the situation from becoming harder for the agent to resolve.
Before contacting support, please confirm
Screen status
Was the screen on an active license and showing as LIVE? A suspended, deactivated or preview screen will not migrate successfully, and this is useful context for the agent.Device history
Has this device been through a migration attempt before? Repeated attempts on the same device are a common trigger for this error.
What to avoid after seeing this error
Do not delete the previously paired device
Leave the Chrome app player pairing in your ScreenCloud account. Deleting it removes information the agent needs and can complicate the resolution process.Do not delete and re-add the IWA player
This will not resolve the error, since only a support agent's action can clear the underlying migration state, and repeating the process can create further duplicate migration flags.
