32 bit to 64 Bit in place upgrade ?

[Arfer]

Hi, is it possible to do an in place upgrade from Windows 7 Ultimate 32 Bit
to Windows 7 Ultimate 64 Bit using full retail DVDs.
I know I will have to update progs to 64Bit but there is plenty else which will not be affected.
TIA

You cant do an in place upgrade from 32 to 64bit... The drivers are completely different as would be the registry...

A side note:

There are few 64 bit applications. Most, but not all, 32 bit apps will run cheerfuly under X64.

An upgrade-in-place is still forbidden, though.
