I'd really like to see an update for Fast Skill since that was the one that I used in TQIT.. but I didn't have Autohotkey, just the program itself was able to work without any issue..
The program still works!! >:D
There is a simple workaround:
FastSkill.exe scans for application with caption 'Titan Quest: Immortal Throne'
So we change AE exe caption from 'Titan Quest Anniversary Edition' to 'Titan Quest: Immortal Throne'. 8)
Back up your TQ.exe. Now edit the exe in hex editor. I use Hex workshop.
Search for string 'Titan Quest Anniversary Edition' and replace it with 'Titan Quest: Immortal Throne'.

Note after throne put 00 00 00. Because AE name is 3 character bigger than IT name.
Run the game with new exe and run FastSkill.exe. Enjoy fast keys!!
Instead of modifying game exe I could've modified FastSkill.exe, but the author has encrypted the strings in exe.
He could've easily made game caption configurable, but instead he released two exe for both game versions. :-\
@Hector the author posted FastSkill for TQ and IT. Now both the links are down. If you have TQ version then share. I'll compare both FastSkill exes and see if I could modify it to make it work for AE.
