Hello, I seem to have a problem activating W7 on Samsung X420 laptop. Originally it came with an English version of W7 Ultimate. I have made a Ghost image as a fail safe, re-formated the HDD and installed an Italian OEM version. Now Iam unable to activate. I have extracted the original certificate from the English installation and used the OEM SLP from the internet. No joy. I have then tried to use the certificate available on the Internet, but that didn't work either. Basically, everything seems OK. The BIOS SLIC checks out as 2.1, the certificate installs OK and the SLP also. Why the activation doesn't work is beyond me. I have also tried to reinstall the cert using SLMGR.VBS -rilc, but that didn't help either. I know I could just add the Italian locale to the US version, but that would mean avoiding this problem, not solving it. And I want a clean installation with no trial rubbish on it anyway. Any ideas what could be wrong or what else could I try?
