ka tik susiduriau su viena problema, kuri kai ka gali atbaidyti nuo 
64bit win7:

jei instaliuosit is CD, kuriame rasoma: 32bit ir 64bit - tai is sito DVD 
NEGALIMA upgreidinti 64bit sistema i 64bit.. t.y. jei kas nutiks su 
64bit sistema - "upgreidinis" taisymas nepavyks..

kodel?

"if the media contains both 32-bit and 64-bit on the same DVD (there are 
a few programs like MSDN that may ship media like this), what happens is 
that you are running a 32-bit setup.exe.
32-bit setup.exe can install either 32-bit Windows or 64-bit Windows but 
32-bit setup.exe cannot do an upgrade of a 64-bit OS.

The only way this media can be generated with both platforms is to use 
32-bit setup.exe ( you cannot run a 64-bit setup.exe on 32-bit copy of 
Windows).

Since you are running inside 64-bit Windows you are getting the message 
about the upgrade from 64-bit to 32-bit is not supported.
