Permission for a second account?

[Budder]

Hello. I recently got a house with my girlfriend and her kids. Id really like to get her and at least one of the boys into playong EQ with me but I thought multiple accounts from the same IP address would be looked upon as “boxing”. Would it be possible to do this and if so what’s the best way of getting the files on their computer from mine? I tried copying the EMU folder onto a an external hard drive to put it on my old game computer and got an GUI.exe or something error. No idea what happened there...

Thank you, Renlaan
