I'm using an older software for an older drone, but the driver signature problem is the same for any other unsigned DJI drivers, so this may work for all of their older unsigned drivers. Windows will ask you do you want to accept these unsigned drivers. Then after the pc reboots, reinstall DJI assistant 2. Couldn't get DJI RC Assistant version 1.2 to work with a direct connection to the RC unit with USB, but I can still charge the unit that way. I suggest Googling disable driver signature for Windows and that will walk you through the steps needed. Using that software I calibrated the RC through the drone. When I logged into the computer out of safe mode, the Vision Assistant 3.8 Software linked to the drone. In safe mode Windows didn't see the drone or the RC when plugged into the usb port, but I installed anyhow, thinking the usb channel I was using was disabled in safe mode. The only way that worked was booting into safe mode and installing the driver. License server utility to support floating licenses for. I tried disabling driver signature verification, shutting off virus protection, launching the installer as an admin, and all kinds of other stuff. Note: At the moment Metashape 2.0.0 works with node-locked licenses only. If you are unfamiliar with the device and driver installation process, we recommend that you start by reviewing Roadmap for Device and Driver Installation. I was getting the 'This App has been blocked for your protection' error when trying to install the drivers on Windows 10. This section explains how devices and drivers are installed in Windows.
