I have a new computer on which I have installed Win 7 32bit which is working fine.

However as the computer is quite powerful with an Intel i7 processor and 6gig of 1600 DDR3 ram I am sorry now that I did not install the Win 7 64bit version.

Would there be any problem installing the 64bit version over the 32 bit version?

Cheers.

As far as I know, you won't be able to do that. It's a fresh install unfortunately, but on a system like that I would strongly recommend x64 otherwise the power goes to waste :)

Ian - thanks for the reply - perhaps I did not put my question very clearly.

I have Windows 7 Home Premium Edition and would like to know if I can change from 32bit to 64bit by just inserting the 64bit disk in my hard drive and install it "instead of" the 32 bit version, i.e a fresh install?

Would I require any preparation of the hard drive before doing this or is it just a matter of inserting the 64bit disc into the drive and following the on screen instructions?

Thank you.

It would be in your best interest to format the drive when you are asked to choose a location for the install. This will wipe the drive so be sure you have all your data off before doing so.

Many thanks for the reply - since my machine is virtually brand new I am not too concerned about loosing existing data - although I will have to re-install quite a few programs.However your further advice regarding formatting the hard drive would be appreciated, i.e I cant remember being asked to choose a "location for the install"and if I am asked the question - how do I proceed with formatting the hard drive?

Thank you.

Hi there Clifford,

Can I upgrade Vista Home Premium 32 bit, to Windows 7 Pro? Also is Windows 7 Ultimate a 32 bit or 64 bit OS? Thanks for your answer!

Yes, you can upgrade Vista Home Premium 32bit to Windows 7 Pro, but only in 32 bit.
IF, you do a clean install you can go either the x86 (32bit) version or x64 (64bit).

Since your computer is x64 capable, then I would do a clean install of the x64 version. It will utilize the full capabilities of your CPU and RAM to the fullest. The x86 version will only recognize up to 4GB of RAM, the x64 version will recognize all of your RAM. You have quite a beast of a system so there is no reason NOT to install the x64 Windows 7.

Windows 7 Pro and Ultimate come with both the x86 and x64 install disks. (Retail boxed versions only.) The OEM versions are sold as single discs, either x86 or x64.

It may just be that you need to format the HD first or your laptop may only have a 32-bit processor, in which case it cannot run a 64-bit OS. If you tell us the model number we might be able to find some more information.

Also how much RAM does it have?

Before formatting or installing, make sure you have first backed up all your settings and data to an external drive or disks. The easiest way to do this is with the Windows Easy Transfer (WET) utility.

If it turns out your laptop will not support 64-bit, note that you can download 32-bit Home Premium and install it using the key that came with your new 64-bit disk.

My suggestion is to make sure you have it all backed up and then format the hard drive. Then boot to your install DVD. Hopefully that works.
