Frequently Asked Questions – Cities Skylines (v1.21.1-f9)

Is Cities: Skylines completely free?

The package listed here is offered as a free download at version v1.21.1-f9. Note that the official Steam edition is a paid game — Valve lists Cities: Skylines as a paid title, not free-to-play.

How do I install Cities: Skylines from this package?

There is no setup wizard. Extract the archive to a folder excluded from your antivirus, install the apps from the Redist or _CommonRedist folder, then launch Cities Skylines.exe inside the game folder as administrator. Full details are in Installation Guide.txt.

Does this download include the DLC expansions?

No. This is the base game package. The site admin has confirmed mods are not part of the download either, so you would need to source expansions separately.

Which platforms support Cities: Skylines?

Valve lists Windows, macOS, and Linux support for the official Steam edition. This package is listed for Windows, macOS, Linux, Android, and iOS.

Why does the game crash a few seconds after launching?

In our testing, the most common cause was skipping the Redist folder installation or extracting the archive inside an antivirus-scanned directory. Install the redistributables first and run the executable as administrator.

Can I use mods with this version?

The official Steam edition supports Steam Workshop and an included level editor. This package does not, and the site admin has stated they do not work on mods for it.

Installation Guide

Step-by-step setup process

Game is pre-installed / portable, therefore you do not need to install the game.

Just extract the rar / zip file using 7-Zip or WinRAR.

Simply launch the game directly from the game executable as Administrator.

Important Notes

Install necessary apps from Redist or _CommonRedist to ensure game launches without problems.
Always extract game in Antivirus / Defender excluded folder to prevent false-positive file quarantine.
Always run the game as administrator.
