Welcome to Windows Seven Forums.

You cannot upgrade from a 32-bit version of Windows to a 64-bit version.

If you want the 64-bit version it has to be a clean install.

thank you :)

i am trying to do a clean install i get the error code when the file are expanding

Have a look here, in particular, Option Four.

Clean Install with a Upgrade Windows 7 Version

What installation media are you using?

If it's an ISO, it may be a bad burn so you might want to download another ISO and burn that one.

it is a DVD but i have tryed to download the eval version still the same so im ruling out the DVD and the drive

You cannot use the evaluation version to clean install Windows.

You need to buy the full version, and then carry out a clean install.

yeh i know i was testing to see if it was the disk or not :)

i have now managed to get past that stage buy changing the sata to AHCI my pc now BSOB when windows 7 boots up

Did you buy Win7 Student version, and have you downloaded the ISO for the licensed version?

If so burn it to DVD or write to flash stick using Windows 7 USB-DVD Download Tool.

Then boot the DVD or stick to Clean Install Windows 7.
