Hello, I have been Norton user for many years. Recently, I bought a box version of Norton Security in Japan. When I travel to another country, I get a critical warning message saying that my serial number is invalid. Norton told me that their software checks to make sure that the user uses the software in the intended country. Personally, I find this ridiculous as quite a lot of laptop users travel abroad. They cannot expect us to buy different versions of the same program whenever we travel to a country. Also, as all of my software and Windows are Japanese version, installing non-Japanese version of Norton might cause compatibility issue. Any suggestion besides looking for products from another company?
