Hi!!
Today at the fair automation Automaticon 2012 (Warsaw, Poland) talked with representatives of Siemens. It is like you said. Siemens does nothing against Hanover. I have to wait for the 2nd half of the year. The question is not it better to buy what is now and re-install the system on 64-bit. The question is what the OEM agreement for Windows 7? As originally installed in the PG 32-bit, then you can install 64 and have no legal problems with the license of Windows 7 A reinstall of the system is not a problem if one uses the integrated projects, Step 7 and WinCC 7.0 ... :-)
Thx
Bye
