Group Policies

If your organization uses Group Policies for browser extension management then follow the instructions from this page to ensure that the Extension for Chrome is installed correctly.

The list of active policies on your machine can be viewed in Chrome by navigating to chrome://policy.

You can find out more information about Chrome policy management on this page.

Group Policies that affect the UiPath Extension for Chrome

ExtensionInstallForcelist

The ExtensionInstallForcelist policy controls which extensions are force-installed in the browser.

This policy must contain the ID of the extension for Chrome.

• For machines that are joined to a Windows Active Directory, follow the installation steps for the Group Policy Offline installation method.

  For the offline installation method, the ExtensionInstallForcelist policy must contain the value:

  ndmegdjihnhfmljjoaiimbipfhodnbgf;file:///C:/ProgramData/UiPath/UiPath.Common/ChromeExtension_SelfHosted/extension_manifest_chrome.xml

• For machines that are not joined to a Windows Active Directory follow the installation steps for the Group Policy Online installation method.

  For the online installation method, the ExtensionInstallForcelist policy must contain the value:

  pgbnimfaaifjpebleldfhgcjdnaeafdi;https://clients2.google.com/service/update2/crx

NativeMessagingBlocklist

The NativeMessagingBlocklist policy prevents the UiPath NativeHost (ChromeNativeMessaging.exe) from working.

If the NativeMessagingBlockList policy is defined with the value of *, it means all native messaging hosts are denied, unless they are explicitly allowed through the NativeMessagingAllowList policy.

NativeMessagingAllowlist

The NativeMessagingAllowlist policy specifies which native messaging hosts are not subject to the deny list.

A deny list with the value of * means all native messaging hosts are denied. You can allow the UiPath NativeHost by adding the value com.uipath.chromenativemsg_v2 to the NativeMessagingAllowlist policy.

ExtensionInstallBlocklist

The ExtensionInstallBlocklist policy prevents extensions from being installed on the machine.

To fix this, you can either:

• Install the UiPath Extension using Group Policy.
• Or allow the UiPath Extension to be installed from the Chrome Web Store by adding the value pgbnimfaaifjpebleldfhgcjdnaeafdi to the ExtensionInstallAllowlist policy.

NativeMessagingUserLevelHosts

If the NativeMessagingUserLevelHosts policy is set to false, it prevents the UiPath Extension from working correctly in the case it was installed without administrator privileges.

To fix this, you can either:

• Install the UiPath Extension using Group Policy.
• Or set the NativeMessagingUserLevelHosts policy to true.

BlockExternalExtensions

If the BlockExternalExtensions policy is set to true, the UiPath Extension can only be installed from Group Policy. To fix this you can either:

• Install the UiPath Extension using Group Policy.
• Or set the BlockExternalExtensions policy to false.

ExtensionAllowedTypes

If the ExtensionAllowedTypes policy is set, it prevents the UiPath Extension from being installed. To fix this, you must add the value extension to the ExtensionAllowedTypes policy.

ExtensionSettings

If the ExtensionSettings policy is set to block all extensions it will prevent the UiPath Extension from being installed.

To fix this, you can either:

• Install the UiPath Extension using Group Policy.
• Or allow the UiPath Extension to be installed from the Chrome Web Store by adding the value pgbnimfaaifjpebleldfhgcjdnaeafdi to the ExtensionInstallAllowlist policy.
