Hickory: One must assume you are talking about in GOG Galaxy. I don't know the answer, but considering all but patch 2.0 has been removed from the download section, I would have to say "no".

pbnjoe: I asked support if there was a way I could get the installers/patchers for 1.3 a couple days ago and received the response that "that version is no longer available".

There is an option to rollback in Galaxy but it's not clear what it is. The options for rollback are 2.0.62.2 from 6 days ago (the current version) or "26566739" from "a year ago", whatever that is. I don't have time to test it out now to see what game version that is nor if it works at the moment unfortunately, but I guess that means that *something* can be rolled back to.

Edit:
Looking at my BGII:EE entry's config in Galaxy, which I downloaded and installed the 1.3 version of when it was available, currently states that there's an update available and has the second option for rollback already ticked, which is "26566974" from a year ago as well. I suppose this would mean that these odd numbers represent 1.3 for both games?

pbnjoe: I don't have any BG2 saves at the moment, but since the 1.3 installer, which had been out for ages, matches up to the rollback choice (with the second rollback being ticked and whatnot) I'm confident that it will/would work fine, likely for either game. See the last paragraph for good news.pbnjoe: Without using Galaxy, yeah :\ you can undo the majority of the graphical changes that 2.0 brought (character outlining etc.) in the options menu but as for bugs, it's just a matter of waiting I suppose. In my 6-hourish experience the only one I noticed was the difficulty-lowering one though, and from what I've read it seems to only occur when you enter the options menu while playing.

Hey, I decided to take the time to roll back for you guys, and it turns out that the weird number version indeed BGI:EE 1.3.2053! My saves for the game load just fine. Hope that assuages your fears :)

Paulo201088: Thanks for the confirmation mate. Now I can buy the EE without fears. (^o^)

hiliev: This is not a solution. If the original 1.3 installer is no longer available at GOG, then it means that you can only rollback as long as the old version is still installed on your computer. I just rollbacked my BG2:EE and Galaxy downloaded 950 MB of data, which means that the 1.3 (26566974) files still exist in one form or another. But if GOG is unwilling to make them available in the form of an instlaler, it will put me in the very awkward future situation of having to search for unofficial sources (you know what I mean, wink, wink) of a game I've paid for and technically own.
