If you really downloaded the RC, the best way is to do an "in-place" upgrade from your installation disk. Could be that you somehow conserved files from the Beta version that lead to that mismatch. The easy way to check: All your system files must be from 04/22/2009, if there are older versions, you may encounter the problems you report.Mobile AMD64 3000+, VIA Apollo K8T800 chipset, 1 G RAM, ATIRadeonMobility 9700, 20x DVDRW, C:XPSP3 (55G),D:WIN7 (25G),F:DATA (250G)

You have to Activate it online, not register it online. That's 2 different operations. Search around and you will find Activate online.

well i also activated it online also.it showed that activated successfully.but again nothing happens

thanks for the info. i will try this approach

Make sure your time zone and date are configured (wild guess).
