I'm not sure you realize it, but you skip over some vital elements in this video. I have actually watched this video before. wait until a later step and I will show how to do this method. If you installed your copy of Diablo II using your OWN keys or keys that WORK and you want to use those. Use the cd key set that was used with your Diablo II install. The file names must match exactly! EX: d2key1.mpq Leave the "Classic" and "Expansion" sections blank. mpq file we copied over to our diablo 2 folder earlier. This name is for the bots identification purposes and does not affect the game. Click in the text box that has a + sign next to it and type whatever name you would like for this keyset. Ex: ImageThen we will find the "Keys" button and click it. mpq files you must place them in the Diablo II folder you are going to use for this bot. mpq file keys- This is primarily used if you create cd key files via the key creator or you made them with Etal etc. Next copy and paste or type out each of your classic and expansion keys in the next two text boxes labeled as "Classic" and "Expansion" Then click the "Apply" button. Next click the "Name" text box this name WILL be shown in game for the name if someone tries to use these keys and gets the "In use by key name" error.

Manual addition of keys- Click in the text box that has a + sign next to it and type whatever name you would like for this keyset. You do not need to use multiple methods for the same key. Swapping them out or changing them around often has presented me with problems.

What has worked best for me is set up each profile with its own key, run them only with that key, and let the bots run. It can say something to the effect of "This key is in use by so and so" This is something on blizzards end and may be intentional to not allow keys to be switched out to rapidly. Also sometimes you will have an error or interaction if you will when swapping out keys quickly or right after you used them on a different profile. If you want each bot to only use one set you would just need to go through each profile and select each set separately and make sure they don't have the same one. If I understand correctly it looks like you might have done that already. Just to Clairify you are using 5 Diablo II installs because if you try and use one and launch 5 from it that gives you issues? Do you have the cd keys added to kolbot? Not the installs the actual keys themselves.
