Along with the serial are you installing the Asus certificate that matches your slic 2.1 table? Try this - search this forum for the slic tool kit, run it to be sure you have slic 2.1 in bios. If this checks out ok, try downloading and running windows loader. with slic 2.1 in bios it will install the serial and certificate to activate.
Thanks for all help . I dont want to use Windows Loader yet. I'm curious about how things work. Now my Windows is activated Thanks Do I need to leave the cert in root or is it ok to delete it after activation?
windows loader will not install if a SLIC BIOS is detected... it will attempt to activate and install certificate automatically, instead of having to run slmgr manually
Thats great news you got your windows activated. And the best thing is the satisfaction that you did this by your own research. It would be great if you could post back on how you resolved the problems. This might just help someone else. BTW - I to leave the cert after activation
