Hello to all ! I have one disk with windows 7 64bit installation, and I use this single installation betwenn 2 pc, (with ejectable disk). Now I'm not able anymore to activate my copy, I have end online activation and phone activation. I have 2 genuine serial, but i think need 1 serial multi-license. Need your advice, don't know how do, and I don't want to use windows loader 1.9.2 'cause I have 2 genuine serial. There is an option to activate windows with 2 key for 2 hardware at same time ? thanks !!!!
