    Unhappy Error code 1603, need help...

    I get error message: "1645: Error installing Microsoft(R) .NET Framework, Return Code: 1603". I searched the knowledge base and found the following:

    Cause 1: If setup.exe is used to install the .NET runtime, and it fails, setup.exe will give error 1645. Return code 1603 - Fatal error during installation. A fatal error occurred during the installation of Windows Installer. The installation of Dotnetfx.exe cannot proceed.

    Cause 2: this error warns the end user that files installed on the system are not removed at rollback time. This is because, after a certain stage of copying files over, the rollback feature will not remove them from the target system.

    But I did not find any files left on my machine. And I also check there is no related thing on registry.

    Do you have any suggestion that I can fix the problem?
