32bit instead of 64bit

[mallard1234]

Hello
I bought a computer without the windows 7 installation disk and when I first started up was given the option between 32 and 64 bit. I choose 32 bit, but now I want to change it to 64 bit. Can I reinstall the 64bit straight from my hard drive or do I need to obtain the disc.

Thanks

You have to use the 64-bit install disk.

I had the same problem with my acer. I downloaded a legit windows 7 iso from mydigitallife but apparently they took it down.. Looks like you'll have to contact microsoft or your manufacture for a windows 7 installation disc.

Chanege to 64 bit needs clean install.
