Hey Raj,
It looks like you have the following errors:
MainFrameActions: Packaging (Windows (32-bit)): UnrealBuildTool: ERROR: UBT ERROR: Failed to produce item: C:\Users\\Documents\Unreal Projects\FPSGame\Binaries\Win32\FPSGame-Win32-Shipping_XP.exe
Try deleting your saved, intermediate and config files and packaging again. In the meantime, I will be asking for additional assistance to review your log to ensure nothing major is happening.
Looking forward to hearing back from you regarding the deletion of those files, and whether or not that has solved your problem.
