Ok here is what I've figured out to make a successful run. Based on 1.4a. I'm running Windows 7 64bit.
0. Goto NotAres
pastebin and READ the comments.
UNDERSTAND it. Don't copy things blindly. You will EXACERBATE the problem.
1. Ensure your
screen desktop resolution is set to 1920x1080. I was pulling my hair out for hours wondering why even if I had the client set to 1920x180 Fullscreen windowed the movement waypoints where still ****ed. I finally realized my default screen resolution was set to 1920x1200. And this mess the waypoints up even though you sent the video resolution to 1920x1080 as instructed.
2. Start the bot when AFTER you have clicked RESUME.

its obvious now but wasn't obvious then
3. I downloaded and am using the 64bit AutoIT exe. Get it
here . I run the AutoIt3_64.exe
4. Based on NotAres comments. (Which you read an understood right?) get the support files from the Mediafire link.
5. Install the Imagesearch.au3 into the include folder of the autoit install location. The idea behind the pickLoot function is that you are using a "library" to compare a .png file with a match on the screen. ie. you need to tell the script where to find this library.
6. Copy the pngs to C:\pics. I choose it because. C: drive might be hardcoded somewhere and "pics" contains no spaces. Probably not necessary but hey its working for me. The one thing to understand about the pngs is that they are 1920x1080 specific. If you are running another res you will probably need to make a res specific set. Someone correct me if I'm wrong.
7. Copy the .DLLs to c:\windows\system32 and/or c:\windows\. I have them in both. I had them in c:\windows\system32 (which did not make sense as this the 32bit dlls and the instructions said to use 64bit autoit. But I ain't no coder) that didn't work. So I read somewhere to try sticking it in just c:\windows.
Other things I've picked up.
- My character is slow as I have not the funds to gear up to 25% movement. I have 12% so I DOUBLE the sleep timers on the waypoint moves. Adjust accordingly
- put an
ALTDOWN before checkLoot and an
ALTUP after checkLoot
