# Set Runtime Browser

> `UiPath.UIAutomationNext.Activities.NSetRuntimeBrowser`

`UiPath.UIAutomationNext.Activities.NSetRuntimeBrowser`

## Description

Sets the currently active runtime browser.

This configuration remains in effect for both Modern and Classic activities until either the execution ends or another **Set Runtime Browser** activity is encountered within the same project.

## Project compatibility

**Windows - Legacy** | **Windows** | **Cross-platform**

## Windows and Cross-platform configuration

* **Browser type** (for Cross-platform) - Choose the type of browser you want to be used at runtime. The following options are available: **Chrome**, **Edge**, **Safari**. The default options is **Chrome**.
* **Browser type** (for Windows) - Choose the type of browser you want to be used at runtime. This property accepts only `NBrowserType` variables or arguments.
  + **None** - Enum value: `NBrowserType.None`. The **Runtime browser** project setting (Project Settings > UI Automation Modern > Application/Browser) is no longer overridden.
  + **DefaultOSBrowser** - Enum value: `DefaultSystemBrowser.BrowserType`. Uses the default browser set on the target machine.
  + **Chrome** - Enum value: `NBrowserType.Chrome`. Uses the Google Chrome browser.
  + **Edge** - Enum value: `NBrowserType.Edge`. Uses the Microsoft Edge browser.
  + **Firefox** - Enum value: `NBrowserType.Firefox`. Uses the Mozilla Firefox browser.

### Options

* **Continue on error** - Specifies if the automation should continue even when the activity throws an error. This field only supports `Boolean` values (**True**, **False**). The default value is **False**. As a result, if the field is blank and an error is thrown, the execution of the project stops. If the value is set to **True**, the execution of the project continues regardless of any error.

### Timings

* **Delay before** - Delay (in seconds) between the time the previous activity is completed and the time this activity begins performing any operations. The default value is 0.2 seconds. Adding a delay between activities ensures that one activity has enough time to complete before the next activity begins.

* **Delay after** - Delay (in seconds) between the time this activity is completed and the time the next activity begins any operations. The default value is 0.3 seconds. Adding a delay between activities ensures that one activity has enough time to complete before the next activity begins.

* **Timeout** - Specify the amount of time (in seconds) to wait for the activity to be executed before throwing an error. The default value is 30 seconds.

## Windows - Legacy configuration

* **Browser type** - Choose the type of browser you want to be used at runtime. This property accepts only `NBrowserType` variables or arguments.
  + **None** - Enum value: `NBrowserType.None`. The **Runtime browser** project setting (Project Settings > UI Automation Modern > Application/Browser) is no longer overridden.
  + **DefaultOSBrowser** - Enum value: `DefaultSystemBrowser.BrowserType`. Uses the default browser set on the target machine.
  + **Chrome** - Enum value: `NBrowserType.Chrome`. Uses the Google Chrome browser.
  + **Edge** - Enum value: `NBrowserType.Edge`. Uses the Microsoft Edge browser.
  + **Firefox** - Enum value: `NBrowserType.Firefox`. Uses the Mozilla Firefox browser.

Adding a delay between activities ensures that one activity has enough time to complete before the next activity begins.
* **Display name** - The name displayed for the activity in the Designer panel. A display name is automatically generated when you indicate a target.

* **Private** - If selected, the values of variables and arguments are no longer logged at Verbose level. This field supports only `Boolean` (**True**, **False**) values. The default value is **False**.

## Handling order

The order used for setting the browser type used at runtime is the following:

1. Through the **Set Runtime Browser** activity.
2. Through the **Runtime browser** project setting (Project Settings > UI Automation Modern > Application/Browser).
3. Through the **Use Application/Browser** activity or other UI Automation activities.

## Configure the browser type from Orchestrator

Orchestrator has built-in support for a limited number of base data types, such as `string`, `integer`, `boolean`, etc. For more details, you can check out the [About input and output arguments](https://docs.uipath.com/orchestrator/automation-cloud/latest/user-guide/about-input-and-output-arguments#orchestrator) page.

For data types that are not supported by default in Orchestrator, you must use a JSON representation of that value. For instance, in the case of `enums`, the JSON representation is either the `integer` value of the `enum` value or the `string` value.

To configure an `NBrowserType` argument in Orchestrator, you need to follow the steps below:

1. Create an input argument in your Studio project, for example `in_RuntimeBrowser`.
2. Set the **Browser type** property of the **Set Runtime Browser** activity with the value of the argument.
3. Publish your project to Orchestrator.
4. In Orchestrator, go to **Automations** > **Processes** > **Add Process**.
5. Under **Runtime Arguments**, provide a value for the `in_RuntimeBrowser` argument. You need to specify the browser type in this format: "BrowserName". For example: "Edge". Quotes need to be included. The following browser options are supported:
   * None
   * Chrome
   * Edge
   * Firefox
6. Save the value for the argument. After creating the process, the value determines the browser type used by the automation.
