Rollercoaster Tycoon 3 auto patcher error

Rollercoaster Tycoon 3 has an in built auto patcher that you can run to get the latest patch from Atari. In some cases when trying to patch automatically you may encounter the following error:

"Neither command line parameter specified is an directory."

To get around this follow these steps:

  1. Download and manually install retail update 3.
    Download link 1 <– AtariĀ (US version)
    Download link 2 <– AusGamers (US version)
    Download link 3 <– Fileplanet (EU version)

If you’re curious the error is likely due to having an invalid character in your file path (in this case a copyright symbol). If you want to be able to update automatically reinstall the game and when prompted for the installation directory remove the copyright symbol from the path. For more info see:

If you have any trouble patching the game to the latest version manually, post the issue you are experiencing in the comments below. The more detail the better!
