Guys see if you can help

Ive been involved in the last two Betas and perusing my Zenimax folder in programme files I notice I have two ESO installs. One is from the first Beta I participated in, ie the one before this one and it is a US install. The second one, for the Beta this past weekend is a ESO EU install. Now I live in the EU and will play on the EU server when I get the game (pre-ordered) so my question is can I delete the US install safely?

Thanks

Delete or keep it for the time being. Both contain the same content. But your launcher might try to download it if you delete it.

Thanks. Im guessing all will sort itself out upon release for the early access guys.
