First of all, excuse my English. Well, I have two very simple questions: 1. Is a key for SL edition the same for both 32 and 64 versions? I mean, if I have a valid key for 64-bit version, can I use it to install a 32-bit one (and vice versa)? 2. Is only difference between SL and "plain" 8.1 an inability to change a language for UI? Or it has some more restrictions? Thanks in advance!
