Hi all, on my Notebook (Fujitsu - Siemens) is installed Vista Business (is a bundle with pc, I have the recoevry CD). I need to install the 64bit version legally: it's possible using the same version (and language)? I read a post about creting a OEM DVD copying the $OEM$ dir from existing DVD to the new 64 bit DVD. I can do it with EVERY version of the new DVD (retail, volume) or I need the OEM DVD? Thanks for support!
