I live in Mexico but spend a couple of months in Michigan each year. I have a laptop in Mexico and have NIS 2012 installed in the Spanish edition for 1 license which will run out in Feb. 2013. I just bought a new computer for home in Michigan and need to purchase NIS 2012 for it. If I buy a NIS 2012 (English version) from Amazon.com CD with permission for 1 user and 3 computers can I install it in the computer in Michigan now and in Feb. 2013 install it in the computer in Mexico. Should I use my Latin American Norton account to register new English version or set up a new U. S. account?
