Thank you for contacting us and I'm sorry about the issue you are experiencing. Can you let me know what you mean when you say it's impossible to activate mSecure on your tablet? What version of mSecure are you trying to use on your tablet? Are you referring to mSecure 5 and it's authentication process? If so, what happens when you try to authenticate? What authentication option are you trying to use? Do you get an error message? If so, what does that message say?
