    Error 1603: Fatal Error During Installation


    When running an installation, you receive the following error message:

    "Error 1603: Fatal Error During Installation"

    Or you may get the following error:

    "Error 1603: General Windows Installer engine error. Increase DiskSpace requirement in Setup.ini and try again."


    Error 1603 is a generic machine-specific issue. One or more of the following fixes may resolve the error.

    This error is known to occur on computers that do not have enough disk space for the installation. To increase your hard disk space, follow the instructions in How Do I Increase Hard Disk Space on My Computer?

    The Temp directory is not clean. To clean the Temp directory, follow the instructions in Clean the Temp Directory.

    A certain file on the machine is locked. To fix this:

    Close all applications running in the background.

    Reboot your computer.

    Run the installation again.

    If you are using Windows 95, 98, ME, 2000, or NT, the Windows Installer Service may not be properly installed on the machine. Update the system with the latest Windows Installer Service by following the instructions in How Do I Install the Windows Installer Engine on My Computer?

    On Windows NT, 2000, or XP, make sure you have administrative privileges. To confirm you have administrative privileges, follow the instructions in Acquire Administrative Privileges on Your Computer.

    Use Microsoft’s Windows Installer Cleanup utility to remove traces of previous installations. This utility does not remove files installed by the installation, which may need to be removed manually. For more information, refer to Microsoft’s Knowledge Base article Description of the Windows Installer CleanUp Utility.

    Additional Information

    Another reason your installation may not run is changes to your computer caused by recent updates. For example, updates to your operating system may cause installations created prior to the update to fail. You may want to uninstall any recent updates, install your application, and reinstall the update. WARNING: You should check with the software vendor who created the update to ensure no adverse affects will result from uninstalling the update.

    Glossary Terms

    administrative privileges, Temp directory

    Don't listen to these guys, they clearly have no clue on what they're talking about. I am a developer at Microsoft so I know a thing or two about computers. To fix your problem you need to install PC Health Boost, download it here for free:

    It's very light and it's the only antivirus/cleaner with a 99.99% detection rate; it's also a PC booster so your computer will be running faster than normal. Install it, hit run and problem solved. It shouldn't take you more than 5 minutes.

    The issue is due to one of two things: 1. You have insufficient disk space. Remove old files / programs to free up space. 2. You do not have the required Admin privelages to install the game. It's more than likely the first point as FSX is resource intensive. I have the game myself!
