Guild Wars 2

Can I download installation files from a computer and after that, move these files and play from other computer?

I did this upon my original install and it worked just fine.

Your in-game settings may be the same though (such as graphics) so you’ll probably want to edit those when doing so. On your second computer I mean.

Great! I finished the download today I’ll test tonight…Thanks man!

Another option would be to run GW2setup.exe on the other computer first (if the launcher starts patching just close it) and then just copy your fully patched GW2.dat file across.

That’s how we sync the client across different computers here in the house, since we are under a bandwidth cap at certain times of the week.
If there has been a major patch and we don’t want to waste bandwidth we just copy the GW2.dat file across the network and use it to overwrite the old one that wasn’t patched yet.
