Windows 7 - 64 to 32 bit downgrade

I currently have vista ultimate 64 bit, and I own a windows 7 professional 32 bit thanks to my university.

can I install the 32 bit version of windows 7 over my current 64 bit version of windows ultimate? will I need to do a clean install or will it just upgrade?

also just checking that downgrading from vista x64 to Windows 7 x86 is possible before I try anything.

thanks.

A clean install , we will also need to see your System Specs, Thanks.

As jfar stated, you will need to do a clean install, unless you can obtain a copy of the 64bit version from your school.

250gb hdd
2.2 Ghz
2 gb ram

using a HP pavilion dv6500

does windows 7 run good on HP laptops?

it runs good everywhere... even in an 8 year old celeron 512mb pc lol

but its really offtopic now lol!

If you plan on using the 64bit version you will want to upgrade your ram to 4gb, but other than that it will run just fine..

yeah, well the reason I chose 32bit is because I only have 2gb ram and 64 bit wont work with my schools wireless network.

Then your OK with what you have... and Welcome to the Forums....

It is probably best to leave this alone, but resistance is futile.

Restraint is admirable.
