I just installed Virtualbox 4.2.14 on unbuntu 12.04. I later installed windows 7 on x86 because my laptop is not that powerful. I later tried installing office 2010 (I have a cd) and it simply says: "The version of this file is not compatible with the version of windows you're running. Check your computer system information to see whether you need and x86 or an x64 (etc.)".
Is there a solution to it or should I reinstall windows 7 on x64? Thanks
