Buy or download Total War: Warhammer III only through an official store such as Steam, Microsoft Store, or Epic Games Store. Check the live system requirements and free space, install through that store, then launch once without mods. If it fails, verify the game files before reinstalling.

Confirm ownership and account

Sign into the store account that bought the game or has the required subscription. Check that Warhammer III appears in its library.

Check requirements and space

Open the live store listing, compare CPU, memory, graphics, Windows version, and storage, then leave additional free room for unpacking and updates.

Open current Total War support

Choose the installation drive

In the store library, select Install, choose a drive with enough space, and keep the default folder unless you have a specific library location.

Let the download finish

Keep the launcher open until download, unpacking, and any DirectX or runtime installation complete.

Launch without modifications

Disable Workshop mods and third-party launch options for the first run. Reach the main menu before adding anything.

Install the current graphics driver if needed

If the game reports unsupported graphics, use Windows Update or the GPU maker's official driver and restart.

Verify files before reinstalling

If it closes or reports missing files, use the store's Verify or Repair command. On Steam, open Properties > Installed Files > Verify integrity.

Follow Steam's verification steps

If it does not work

If the store reports no license, check the account and subscription instead of downloading another installer.
If unpacking appears stuck, confirm disk activity and free space before cancelling.
If only a modded campaign fails, test a new unmodified campaign and update or remove the affected mod.
