Cannot find Assistant software so i can use IOC - follow me

looked allllll over the site  - I want to install it on my pc and plug a mini usb to phantom 3 standard and enable IOC  
LINK would be deeply appreciated

You can download the DJI assistant on this linkDJI Assistant V2.1.6 and must enter flight data mode with your P3 via app .

Here is the way of exporting flight record from P3:
First of all, connect your aircraft (USB port at the tail/ head) to a PC, then build the connection among Remote Controller, aircraft, and the DJI GO app.
Next, click “Mode” icon to view the “Advanced Settings”,  click “MC Enter Read Flight Data Mode”. Hope it can help.
