# How to run multiple raft instances
A quick guide to run multiple Raft instances on a single computer with different Steam accounts, ideal for testing multiplayer mods.
I'll guide you through running multiple Raft instances simultaneously. To begin, you'll need:
1. [**Sandboxie-Plus:**](https://sandboxie-plus.com/) Allows isolated program execution.
2. [**A Second Raft Copy**](https://store.steampowered.com/app/648800/Raft/)**:** You need 2 Raft accounts for running two instances.
Let's get started!
## **1. Installing Sandboxie-Plus**
* Download and install Sandboxie-Plus from [here](https://sandboxie-plus.com/).
* Creata a new sandbox, name it as you like and add an access to your drive as shown below.
{% hint style="info" %}
We recommend granting access to the entire drive in the isolated environment because it includes crucial folders like AppData, world directories, Raft Settings, and Mod Loader files.
{% endhint %}
## **2. Duplicating Steam Software**
* Create a new folder for the second Steam.
* Copy your steam folder in this folder (You may want to remove other games than raft in the destination folder).
## **3. Installing Steam in Isolated Environment**
* Run steam.exe in the second Steam folder using Sandboxie-Plus.
* Start Steam in the isolated environment and select "Run As UAC Administrator".
## **4. Starting Raft**
* Log in with your second Steam account.
* Start Raft with "-rml" or through RMLLauncher opened inside sandboxie too; it should work seamlessly!
