Hi! Sorry if I do not know everything about portability and licensing etc but I have a request.
UDK or unreal development kit is free and I wish to run it from USB drive. I have quickly read in the UDK forum and here is a link about it:

Seems there are some registry things happening and sometimes also a post install of physx, directx etc.
For me that right now is not a problem, I just want to have the main UDK that is above 1gb on the usb.
I remember trying to just copy it a long time ago to a usb but could not get the main program to work. I only got the tree generator program to work that is inside the install dir.
Any thoughts about this tool?
