None of those files have to be placed anywhere in particular. I keep all mine in a "Vindi Hax" folder on my desktop.
Easiest guide I can write:
Open up the SinBotv2.303 folder.
Open up the README.txt file. Read it.
Find the section that has the default binds (big long list of Bind "key" "command") and COPY IT!
Now, go to you folder with the injector that you have. (I recommend PerX,
found here.)
Run the injector program, as admin is you need to.
Within the injector program, open the .dll files for injection.
Make sure both Danksole.dll and vin_v5b.dll are in the list for injection.
Start the injection. If using PerX, just run the Vindictus.exe file. If using sinJect, hit the launch button, and wait for the camera shutter sound. THE INSTANT YOU HEAR IT, CLOSE SINJECT!
You should get a little pop-up box for Danksole. Hit Yes.
Wait for the log in screen, don't click on anything after closing sinject
Once you get a little message saying the Danksole was successful, close that.
Alt-tab to the console window.
Right-click it and hit paste. Finish with an enter so that you are on a new line.
Alt-tab back into Vindictus.
Go to the docks, and choose any boat that you want to bot on.
BEFORE YOU LAUNCH THE BOAT, run the SinBotv2.303 bot file.
Once you see the little tooltip in the to pleft of your screen, alt-tab back into vindictus and click the window.
Press your Insert key.
Sit back and watch the bot go.
