I have to install Windows Server 2003 R2 x64(64 bits) from volume licensing CD, but licensing strings are from Windows Server 2003 R2 x86 Retail/OEM version(32 bits). Local retailer suggested that it’s perfectly legal. Is it possible? I think registration/activation will be rejected, as long as Win2k3Servers (x86 vs. x64) are different products . Thanks for future clarifications .
