Problem installing Improved Anvil v6.5 Options

[Yanosh]

I am new to modding Baldur's Gate 2 so I'm not sure if I am doing everything OK, but I had some trouble trying to install Improved Anvil v6.5 today.

I first tried version linked here in the following thread http://forums.blackwyrmlair.net/index.php?showtopic=5326
However that one didn't have any executable files, so after digging a bit through forum, I found the link to github https://github.com/critto-bg/ImprovedAnvil
This version had both ImprovedAnvil folder and Setup-ImprovedAnvil.exe executable.

But now I have the following problem:

CODE

[*****\Baldur's Gate II Enhanced Edition\Setup-ImprovedAnvil.exe] WeiDU version 24600

SKIPPING: [Improved Anvil]
        The mod requires the game to be patched to v2.0 or higher

Press ENTER to exit.

Not sure why am I getting this message. I have a fresh install of BG2:EE, and I have chosen beta 2.5 as game version.
Can anyone help me? I would really like to try out this mod.

OK. What is this launcher, then? I am not familiar with it. I would recommend downloading a weidu binary compiled for Mac OS X and trying to install mods directly with it. Of course if you're somewhat comfortable using the terminal for this.

One other thing that comes to mind is checking if the weidu binary has executable flag set on.
