Cant upgrade to Vista Ultimate 64bit

[Goudy]

i have had vista ultimate 32bit successfully installed from the get go via upgrade disk. at first i tried to install 64bit but it would freeze up. i later tried again to upgrade from 32bit to 64bit but it wont let me do it from boot up, saying i need to do it while in windows. i tried that but all i got was a window saying i cant run the disk from windows and to do it from start up! i dont know what to do! any suggestions?

my specs are:

mobo: evga 750sli ftw

ram:4GB corsair dominator (only 3gb recognized in 32bit)

gpu: 7950gt OC (i need to upgrade lol)

HDD:1TB, 250GB, & 160GB

CPU:Dual-core 2.13 OC'd to 2.7

any suggestions would help greatly.

p.s. im not sure if i posted in the right topic, sorry if i didnt.

thanks in advance!

Here is an answer from Microsoft:

"If you are currently running a 32-bit version of Windows, you can only perform an upgrade to another 32-bit version of Windows. Similarly, if you are running a 64-bit version of Windows Vista, you can only perform an upgrade to another 64-bit version of Windows Vista."
