  • Please tell us what game and what version, and if you can, what version of the .NET Framework it tries to install.

    Also, please tell us what version of Windows you have.

    We need this information because Error 1603 is a common message that means "fatal error during installation", and the number alone provides no insight into the problem.

    Thanks in advance for your responses to the questions above.

  • Dear AnnaHussie,

    Have your problem been resolved?

    If not, would you please let us know your Windows and .NET Framework version?

    You can use the .NET Framework Setup Verification Tool to verify the installation status of the .NET Framework which report the 1603 error. And if the verification failed, you can:

    Download the .NET Framework standalone installer from:

    As you might know, some versions of .NET Framework are installed as system components. So if you are using Windows Vista/Server 2008/7, you can go to Control Panel\Programs\Turn Windows features on or off to repair/reinstall the .NET Framework. For more information, please see:

    If you are using pervious version of Windows, or want to install the .NET Framework 4.0, please follow the installation tips below:

    Before install, please finish the steps below first:

    o   Turn off your anti-virus/antispyware software during installation;

    o   Install the latest Windows updates from the Windows Update site:;

    o   Complete or dismiss Windows Update before installation. (And don't forget to turn it on later)

    o   Clean your %temp% folder (Start Menu >> Run >> Type "%temp%);


    And please run the setup with Administrator privilege: right-click the installer -> Run as administrator.

    I hope this helps.
