PT12 install problems. Error message* import DLL cfind.dll cannot be loaded*

Hi All

I took out a monthly protools 12 subscription on saturday. Ilok arrived this morning (wednesday). Impressed.

I have downloaded the various Pro tools 12 software, put the ilok in the usb port and downloaded the ilok licence manager but protools wont load. I get error message: "import DLL cfind.dll cannot be loaded".

Please help. I have double checked and I have downloaded all the available elements.

My system spec is as follows:

Processor: Intel Q9550 2.83Ghz Quad-Core.
Processor Cooler: Xigmatek HDT-S1283.
Graphics: XFX ATI Radeon HD4850 XXX Edition 512MB.
Memory: Corsair XMS2 DHX 8 GB : 2 X 4 GB Memory - DIMM 240-pin - 800 MHz (PC2-6400).
Motherboard: Gigabyte GA-P55A-UD3R
Storage 1: Samsung SpinPoint F1642 640 GB.

Thanks!
