Hello, how can I find this version? its not showing up...i only see the enhanced editon, which i dont want to purchase. thanks in advance.

Looks like it's bundled with the EE. You can open a ticket and ask GoG staff for a discount to just get the original. You can also get the disc from Amazon:

You cannot buy the classic version separately -- it is only available bundled with the enhanced edition. Your only option to buy the classic edition now is to get a physical copy. Amazon has the 3-in-1 compilation for $9.99, which includes IWD 1, the Heart of Winter expansion, and IWD2.

Thats utterly ridiculous

So i purchased the EE edition and i dont see the vanilla version in my library, how do i access it??

Go to the game's download page, click on More, and then on Serial Keys; you will see a serial key listed there. Go to redeem the key and the classic edition should be added to your library.

This also works for Baldur's Gate 1 and 2, but not for Planescape: Torment (where, I believe, the classic edition automatically gets added when you get the EE).

The sad part is you answered me faster than gogs own staff did.....anyway im on the download page, i hit more, but i dont see an option for serial keys at all. I see Abort, overview, settings, backups & goodies, manage installlation, view forum, view support, and view store page. Ive explored all these options and theres nothing about a serial key. Now im getting concerned.....what else can i do?

Just to check: You are using a web browser (as opposed to GOG Galaxy), right? (When I check, the menu, the list is completely different from what you see.)

I was actually using the GOG galaxy app on my pc laptop. When I visited GOG through my mobile phone I saw the serial keys you were talking about. Get this though, I finished installing Icewind Dale and it uses the Baldurs Gate 2 graphics for characters instead of the BG1 like the original! So I went through all that trouble to play something thats not the classic version of Icewind Dale. Im freaking pissed....Im going to try reinstalling and see if maybe something changes...

I am sorry for you but you asked "How can I buy Icewind Dale Complete classic version???" while, in fact, you wanted something else (IWD without extension)...
