>> Have you got AutoHotkey installed along with the scripts.
I have installed version AutoHotkey_1.1.36.02_setup. I don't understand what you mean by "along with the scripts"

>> Is AutoHotket set to Run As Administrator.
Yes it is.

>> Did you edit the menu in bbw64.exe so Reaper can access the Biab commands.
Yes by this commands:

object Track: TMenuItem
Caption = 'T&rack'
object TrackMenuItemID1224: TMenuItem
Tag = 1224
Caption = 'Get Track Info'
end
end

>> Are you using Biab ver up to 1003
My Biab version is 1011 (Audiophile). I noticed that if I open bbw64.exe after compile, save and close the Resource Hacker window again nothing has been changed?? Might there be in new Resource Hacker session the text above ( object Track: ... end)?
