Hi all,
I am sorry if this question has been asked a lot to you, but i just want to know for sure.
Currently i am a Windows Vista Home Premium (32bit) user. I am registered to a site which offers Windows 7 Upgrades for a reduced price to students (Ultimate upgrade costs 60 euro

)
However, the site gives 2 differrent items:
-> Windows 7 Ultimate (32 bit) dutch Upgrade
-> Windows 7 Ultimate (64 bit) dutch Upgrade
As you can see i want to upgrade to 7 ultimate

, which, according to MS official website, should be no problem.
However, I want to change from 32 bit to 64 bit, which requires a clean installation.
Will it be possible to run a clean installation with an Upgrade version of Windows 7?
So can i install Windows 7 Ultimate (64 bit) on a computer which used to run Windows Vista (32 bit)?
Or will i encouter some difficulties?
Please help me

Thanks in advance
