Technical can't run the game

[XanthemForum]

I got myself a file of the game. but for some reason, I cannot launch my game. every time I try to open it, I get an error, saying "Failed to open archive common.MPQ" I've looked around the forums a bit and found some ways to fix it, to no avail (restarting pc, moving folder, disable read-only, always run as admin, delete WTF-file(came back) )
apart from those solutions, does anyone have another way of fixing this issue?

Check if you even have that common.mpq file inside Data folder. Maybe you have to download client somewhere else if it's broken.
