Thx for your response,
This notebook was bought in Singapore airport from Sony themselves September 2009.
I ordered the upgrade for it from Sony direct for this model (was supposed to be "Free", but I had to pay).
This model IS supported and the upgrade comes with a Win7 DVD as well as a Supplemental software CD.
Did EXACTLY as manual said, installed Win7, and then when you have to insert the supplemental CD, this error pops up & ejects the cd.
