Gateway Installation with 4.6D would fail in the title phase. The upgrade would fail because of the bug in GWsetup.exe. SAP recommends downloading r3setup_10.car. This file does not exist, just download R3SETUP_13.CAR, uncar it. I have just one file r3setup.exe and delete the old file & rename this file as GWSETUP.exe Re-run the setup...it should work.
