A required DLL file, CFnd.dll was not found

[sunburst79]

I'm getting this after I installed the AIR box set.

The error pop up occours at the Setting Up Peripherals/Initalizing Controllers and before Initialising Machine Control.

Ive uninstalled 7.4, Reinstalled 7.4

Done a clean unistall of 7.4

Uninstalled 7.4cs5, Reinstalled 7.4cs5

Did reinstalls of the MPTK, DV Toolkit2 and all of the Air plugs.

I Ran all of the Dev Partners, BombFactory, and Digidesign Plug in Updaters.

Moved the plugs to the unused plug ins folder- Moved them back.

I Uninstalled-Reinstalled all my Midi Drivers and rebooted along with downloading and installing the latest Pace Drivers.

Any body seen this particular message? Searching the DUC turned up nothing. Pro Tools itself seems to run fine once the error is clicked through and PT loads.

I could restore from a back up but I want answers What is CFnd.dll? What program does it belong to if not PT? and what is PT dependency on it.
