+If there is no error, or if the server is not crashing directly, you have successfully installed it and can proceed with the other step.
+
+* Go into SPT-AKI installation folder and start the launcher by double-clicking on the `Launcher` executable.

+As with the server, if there is no error message, or if the launcher is not crashing directly you can proceed with the other steps. If not, you may want to read the install guide again and check if your problem can be solved by one of the solutions listed in the [FAQ](./#getting_started/faq.md)
