Select Unity Components

Next, you are prompted to select Unity components to install as shown in the following screenshot. You need to know which components to install, depending on your purpose.


Choose Unity Components – 1


If you use a Prefab or Scene created with Unity on STYLY, you need to install the following components.


Choose Unity Components – 2


  • Windows Build Support (If you use Windows, it will be installed by default).
  • Mac Build Support (If you use Mac, it will be installed by default).
  • Android Build Support
  • WebGL Build Support
  • iOS Build Support


In this example, we are using Windows. Check ‘Mac Build Support’. If you use Mac, there is no ‘Mac Build Support’ component. So, select ‘Windows Build Support’ instead.

Please refer to the following article to learn more about the required environment to upload Prefabs and Scenes to STYLY.


Choose Install Location

Next, choose the install folder.




If there is another version of Unity already installed on your PC, then the same install folder could be selected by default and could be overwritten. If you want to install multiple versions, you need to select a different folder.

And, if you use Unity Hub, the file path will be ‘(specified directory)/Editor/Unity.exe’. Choose a directory that is easy to remember.

Once you choose the folder, the installation will start. It will finish in a few minutes.


Unity Install Finished

You will receive a message once Unity is finished installing. Select ‘Finish’ after receiving this message. Unity is now installed on your PC!
