## Group Policies that affect the UiPath Extension for Chrome

### ExtensionInstallForcelist

The [ExtensionInstallForcelist](https://chromeenterprise.google/policies/#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](https://docs.uipath.com/studio/standalone/2025.10/user-guide/extension-for-chrome) installation method. For the offline installation method, the [ExtensionInstallForcelist](https://chromeenterprise.google/policies/#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](https://docs.uipath.com/studio/standalone/2025.10/user-guide/extension-for-chrome) installation method. For the online installation method, the [ExtensionInstallForcelist](https://chromeenterprise.google/policies/#ExtensionInstallForcelist) policy must contain the value: `pgbnimfaaifjpebleldfhgcjdnaeafdi;https://clients2.google.com/service/update2/crx`

### NativeMessagingBlocklist

The [NativeMessagingBlocklist](https://chromeenterprise.google/policies/?policy=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](https://chromeenterprise.google/policies/?policy=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](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=ExtensionInstallBlocklist) policy prevents extensions from being installed on the machine.

To fix this, you can either:

* Install the UiPath Extension using [Group Policy](https://docs.uipath.com/studio/standalone/2025.10/user-guide/extension-for-chrome#install-from-group-policy).
* Or allow the UiPath Extension to be installed from the Chrome Web Store by adding the value `pgbnimfaaifjpebleldfhgcjdnaeafdi` to the [ExtensionInstallAllowlist](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=ExtensionInstallAllowlist) policy.

### NativeMessagingUserLevelHosts

If the [NativeMessagingUserLevelHosts](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=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](https://docs.uipath.com/studio/standalone/2025.10/user-guide/extension-for-chrome#install-from-group-policy).
* Or set the **NativeMessagingUserLevelHosts** policy to `true`.

### BlockExternalExtensions

If the [BlockExternalExtensions](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=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](https://docs.uipath.com/studio/standalone/2025.10/user-guide/extension-for-chrome#install-from-group-policy).
* Or set the **BlockExternalExtensions** policy to `false`.

### ExtensionAllowedTypes

If the [ExtensionAllowedTypes](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=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](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=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](https://docs.uipath.com/studio/standalone/2025.10/user-guide/extension-for-chrome#install-from-group-policy).
* Or allow the UiPath Extension to be installed from the Chrome Web Store by adding the value `pgbnimfaaifjpebleldfhgcjdnaeafdi` to the [ExtensionInstallAllowlist](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=ExtensionInstallAllowlist) policy.
