I can download and use the Assistant 2 app for Matrice 210 RTK for firmware but cannot use it for Vision Position Sensor Calibration. (UAV Movement in car caused this need to calibrate).
It seems the APP is SIGNED in Chinesse and Windows 10 won't allow it. Tride updating etc. but Exclamation point still there.
Tried Developer mode but No Luck.
Any suggestions?

You can use the advanced boot options menu to boot Windows 10 with driver signature enforcement disabled. This isn’t a permanent configuration change. The next time you restart Windows, it will boot with driver signature enforcement enabled—unless you go through this menu again.

To do this, get to the Windows 8 or 10 advanced boot options menu. For example, you can hold down the Shift key while you click the “Restart” option in Windows. Your computer will restart into the menu.



Select the “Troubleshoot” tile on the Choose an option screen that appears.



Select “Advanced options”.



Click the “Startup Settings” tile.



Click the “Restart” button to restart your PC into the Startup Settings screen.



Type “7” or “F7” at the Startup Settings screen to activate the “Disable driver signature enforcement” option.



Your PC will boot with driver signature enforcement disabled and you’ll be able to install unsigned drivers. However, the next time you restart your computer, driver signature enforcement will be disabled—unless you go through this menu again. You’re now free to install drivers that haven’t been officially signed by Microsoft.
