Portable MS Word Created in VM Ware doesn’t work in Windows 7

I have created a portable Microsoft Office Word under the VMWare application running Windows XP.
When I tried using the created Microsoft Office Word application portable, I have encountered this problem when running in Windows 7.
The portable application works in Vista and XP.
I need the portable application in Windows 7, please help.
