It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

As title suggests, I can't install. Specifically trying Pillars of Eternity II: Deadfire. It goes all the way to 100% and then says Failed to install (E1: Error). I can't seem to do anything to successfully install this game. Tried the IPv6 suggestion that I read elsewhere, but that didn't help. I have restarted, maybe I should try uninstalling GOG Galaxy and reinstalling?

EDIT: I uninstalled/reinstalled GoG Galaxy, and now things are working again.

e1 is the files are corrupt or [more likely] the path is not allowed to be reached.
step 1 is reboot your system... if its doing an update or has just upgraded Galaxy the reboot tends to sort it

otherwise we need info like os system [8, 10 or 11] antivirus and what path i.e, did you install it outside program files folder
