Ran on XP machine and Linux box for long time running Norton Ghost 12.0 with no problems. Downloaded trial version of NG 15.0 from Softonic, but realized had no license key for same and old license key for 12.0 does not work. Is there someway one can purchase a 15.0 license? Is there a reseller out there for old Norton Ghost 15.0 installation CD’s with license keys?
