ONLY APPLY SP4 FOR TRS2004 TO TRAINZ RAILROAD SIMULATOR 2004. DO NOT APPLY THIS SERVICE PACK TO ULTIMATE TRAINZ COLLECTION OR TRAINZ.
Here is the basic guide for installing Service Pack 4 for Trainz Railroad Simulator 2004 to your Trainz Railroad Simulator 2004.
Most importantly, you will need to identify the correct patch for your build. To do this, launch Trainz and look for your Trainz Version Number and Build Number located at the bottom right hand side of the splash screen and note down the build number.
Select the Quit button and return to the desktop.
Important: If your build number is not listed here please enquire at www.auran.com/helpdesk for further assistance, providing your Trainz version and build number.
Download the corresponding patch for your build to your desktop.
Ensure that your Anti-Virus software is disabled.
You will require up to 1.5GB of free space in your temp files (usually C.Drive) for this patch to be successful, depending on which patch you need.
Double click on the file to launch the installation.
Follow the prompts to install Service Pack 4.
This can be a large file and therefore may take some time to complete the installation. It may appear to stall at some points. Do not be concerned. This is not an error.
If you receive an error from the patch program at any stage about missing or incorrect files, the patch has not been successful (even if you then get a Installation Complete message) and you will need to reinstall TRS2004.
On completion of the installation you will see an Installation Complete notice.
Please launch TRS2004. Congratulations on successfully installing Service Pack 4 for Trainz Railroad Simulator 2004.
