# Getting started

Please make sure you have followed the requirements and the specific requirements per operating system:

* [Requirements](https://docs.infotopics.com/writebackextreme/v4.0/installation-guide/requirements)
* [Upgrading? Make sure to follow these steps first](https://docs.infotopics.com/writebackextreme/v4.0/installation-guide/upgrade)

When all requirements are met we can start the application installer. This is different per operating system. Follow each step in the guide of the desired operating system:
