The error message you are seeing indicates that the version of the KERNEL32.dll file on your system does not contain the "SetProcessMitigationPolicy" function that the OfficeSetup executable file is trying to use. This function is only available on Windows 7 Service Pack 1 and later versions of Windows.
To resolve this issue, you can try installing the latest updates for Windows 7 from Microsoft Update. This should update the KERNEL32.dll file on your system to a version that contains the required function.
