Guild Wars 2

I downloaded the 64 bit client this morning and moved it into my Guild Wars 2 folder but it’s making me redownload the whole game. If you would take a look and tell me what I’m doing wrong. Thanks!

added .exe to the end and it works. Sorry!

Not sure what you did there, looks nearly as if you have the default explorer settings
that hides the extension of files, since i also see a GW2 without .exe
In that case your gw2.dat is in reality maybe gw2.dat.dat and not recognized.

Windows only cuts off known extensions, so stuff like .dat is still showing.
