Here's something that has happened to me and with computers travelling all over the world, now a days, I guess someone could be interested.
Originally I had Norton 2008 in English over a Spanish Win OS. All the updates up to 2010 went fine and in the same language. However, when I updated one of my PCs to 2011 it suddenly recognized the Spanish OS and installed itself in that language. Same thing happaned in the second PC -a laptop.- with OS in Spanish.
Here comes my surprise: I used the same update from10 to 11 in a laptop that has an English keyboard but with Spanish OS and set to Spanish regional time and other settings. NORTON installed itself in ENGLISH !!
I wonder if is taking a snapshotof my keyboard layout, through the "virtual, star wars like, hiden camera at boot and saying "hey, this is English" I can't think of anything else!! Just a joke
It doesn't matter to me but is something that might happen to people who do matters.
Just add: Same settings, same download site, same previous version... All the same!!
