Install the software on a desktop PC then copy the folder(s) to a pen drive.
I'll use KiCAD as an example.
Copy the contents of "c:\program files (x86)\kicad" to a pen drive and run the KiCAD app from within the \bin folder.
I am sure the same goes for Eagle and DT, paths might need to be created when the program first runs, you may be able to change paths, I think you can in Eagle.
Alternatively you may be able to download one of those portable app creators, which takes an installed app and creates a "portable" version of it, I have seen a portable Altium, never tried it, not sure if it would even work that great, it was like a 4GB file.
