Welcome to GTA5-Mods.com

@RevCarl Tobii EyeX dll has to be in GTA V main folder for this mod to work. The reason for this is that Mark & Execute is written as an ASI plugin and it can use only extra libraries from the directory where the Script Hook V is.

I'm not sure what may be wrong in your case, I haven't tested this mod with Steam version. This version has been compiled with latest Script Hook V from September 16th.

@Yavar007 Do you have updated Script Hook V? Do you have "Tobii.EyeX.Client.dll" file in GTA V directory?

@tay1954 drive-by execution is in plans :) Slow motion is already there with "Close Up" and "Simple" kill cams.

@floydandsome I didn't change the version number, because there aren't any changes, I just included one missing external .dll

@floydandsome Change in MarkExecute.ini
menuKey=F3
to anything you like. You can also use key combinations like CTRL+J etc.

Examples:
menuKey=F9
menuKey=CTRL+Q
menuKey=NUM5

@ipwn You probably have the same problem as others above, Mark & Execute asi doesn't load because of lack of Tobii EyeX dll. The updated package is pending approval, but you can download it from here if you don't want to wait: http://www.gta-mods.pl/pliki/782/mark-execute
Just copy & paste .dll file into GTA V directory.

@ipwn When using Xbox360 controller, you can mark the targets only when free aiming (since there isn't really any free button I could use for marking without aiming). I guess I could allow for aimless marking when ducking behind cover.

@floydandsome Hitman Absolution-style execution is next on my TODO list, as a seperate mod though :)

@erielau @lis129 @pedrocosta73 My fault, I forgot to include Tobii EyeX dll with the package. The new file is pending approval now, just copy & paste Tobii.EyeX.Client.dll file into GTA V directory.

@pedrocosta73 I've tested with the most recent version of Script Hook V and ScriptHook .NET v2.3. Do you have Alexander Blade's Script Hook V updated? The mod was compiled with the latest libraries.
