Okay I am not sure if this is the correct board but I will throw it out here anyway.
I was wondering can Wizard101 be installed on a portable 64 GB USB Stick? This would allow the game to be played on any PC that supports the OS that stick is associated with?
I assume it would work, although you would have to make sure all graphical and game files are completely transferred as well as constant updating the launcher.
I did do something similar with my Windows laptops back and forth and it was alright as long as the launcher was up to date. Now I have a Mac OS as well so I'm not sure, but give it a go!
Yes, installing something on a portable drive is no different than installing it on a permanent drive; the computer is just retrieving files from a different location.
