If the browser you're playing KanColle on is set to allow saving cookies, then you only have to do the editing once since the cookie is saved wherever your browser stores them. If your browser is set to, say, delete cookies when closing it you'd obviously have to do the editing all over again. Also, the only thing KanColleViewer's "Set Regional Cookie" option does is executing the lines mentioned on this page so that you don't have to do it manually. And since KCV is running the game in Internet Explorer, you obviously have to allow it to store cookies.

As for those error messages you mentioned, I honestly have no idea since I'm using only KCV with the aforementioned option.
