Fix: AtlasOS Playbook Stuck at “Reticulating Splines”

During the implementation of the AtlasOS Playbook, the setup can get stuck on the Reticulating Splines screen. Here, the setup often goes through various dependencies and other utilities to be downloaded via the curl utility. However, an inconsistency can cause this issue to get stuck in which case you will have to reinitiate the current process.

AtlasOS offers a minimal and optimized Windows experience especially put together with gamers in mind. As such, it provides a higher framerate and better performance by debloating a generic Windows installation. The operating system uses playbooks to deploy the required configuration on your computer to help you achieve better gaming results. You can use the following methods when this configuration is stuck to mitigate the issue. 

1. Let the Setup Run for an Hour

The first thing you should do when starting to troubleshoot the issue is to not touch the setup at all. In some cases, the setup process is not stuck but rather ongoing very slowly which can lead you to believe otherwise. Therefore, we would recommend letting the setup run for an hour at least without making any changes to see if the issue persists.

In case the progress bar does not seem to go any further after that, move the toolbox and playbook files to the Desktop location on your computer and give it a go. Doing so should overcome the issue in most cases and the setup will proceed, even if it is slow. 

2. Skip VCRedists Installation

The reason the Playbook gets stuck at the Reticulating Splines screens is currently due to a bug. The issue occurs when you are missing certain Microsoft Visual C++ Redistributables on your computer and the Playbook setup is trying to download and install them on your computer. 

For this purpose, the curl utility is used in the backend. In such a scenario, you can skip the installation of Microsoft Visual C++ Redistributables to resolve the issue. Doing so will resume the Playbook progress and you can deal with the Redists on your own afterwards. 

Follow the instructions below to skip VCRedists installation:

  1. First, open the Task Manager. You can do so by right-clicking the Windows icon and choosing Task Manager from the menu that appears.
    Opening Task Manager
    Opening Task Manager
  2. On the Task Manager window, look for the curl executable, PowerShell and Windows Command Processor processes.
    Windows Powershell Process
    Windows Powershell Process
  3. Select these processes one by one and end them.
  4. After you do that, the progress should resume and the issue will be gone.

3. Manually Install VCRedists then Apply Playbook

Another way you can mitigate the problem in question is by manually installing Microsoft Visual C++ Redistributables beforehand. These are essentially runtime libraries that are required by various applications on your computer that are built using Microsoft C and C++ tools. 

Playbook tries to install these runtime libraries automatically during the setup via the curl utility. As such, if you install the libraries before initiating the Playbook, the problem will cease to exist. 

Installing VCRedist is a straightforward process. Simply head to the official website for VCRedists by Microsoft here. Download the setup files for any missing VCRedists on your computer and run them. The Atlas team has not listed the required VCRedists versions, as such, we recommend installing all the versions starting from 2015. 

If you are not sure of the current VCRedists versions on your computer, open a Control Panel window and navigate to the Uninstall a program section.
