Hello, i upgraded from Vista 32 bit to Windows 7 32 bit, I now need to upgrade to the 64 bit OS. I upgrade box set came with two discs 32/64 bit versions. Can I upgrade using these discs. Booting up with the 64 bit disc does want to do anything except the incompatible oS message. Do I need to by a full version?

you can't upgrade to 64bit from 32 bit OS..
you have to do Clean installation of windows 7 64 bit from the disk you got
^that and make sure your CPU is 64bit otherwise you can't use a 64bit system.
