I finally got the work around to run DJI Assistant so that I can calibrate my sensors on the P4P.  Now that DJI Assistant is running, when I click on Calibration, the button is grayed out and I can not calibrate my P4P.  It just keeps prompting me to restart the P4P.  I downgraded the Firmware from .600 to .300.  I tried using Assistant 2.0.6 and 2.0.2 and same thing on both.  I don't know if the problem is still related to the software certification problem that was preventing it from running or if this is a totally different problem.
I started getting an error message in DJI Go4 that my sensors needed to be recalibrated.  I have turned off Obstacle Awareness and I can fly fine without that on.  Just need to figure out what has happened and see if I can get it fixed.

Thanks for any help!

Hi there, thank you for reaching out and we're sorry to hear about the trouble. With regards to that, you may give a try to uninstall first the DJI Assistant 2 then after that, you need to disable the signed driver enforcement after you disable it, reinstall the DJI Assistant 2. Please keep us posted. Thanks!

Hi Gamora, I had disabled the signed driver enforcement the other day but that did not help.  I then had help on disabling the user account editing the HKEY settings.  That then let me install the DJI Assistant.

What specific steps do you recommend for disabling the Signed Driver Enforcement?  I rebooted and went into special setup and then ultimately pressed #7 to disable the enforcement.  Please let me know if there is another method or another step.

Thanks!

Ok, thank you for the additional info. I assume you are using a windows 10 right? have you tried to use a lower version of windows or Mac if there is? Since if you are using a Windows 10 our developer still working on it and optimizing the software. Please keep us posted. Thanks!

using version 2.0.7 solved the problem

You know, I am fresh out of  old Windows edition PC's laying around.  As a drone pilot, I actually keep up with new releases and new hardware for most of my stuff and that includes Windows operating systems.

DJI obviously does not.  There is something going on here that the public is unaware of.  I have never ever had this problem with any other software so for this to happen and continue to be a problem, there is a much deeper level issue going on.  It  may be a little bit before it call comes out but sooner or later we will find out the truth.  

I'm sorry to hear that and I understand about that. May I ask if you have the latest DJI Assistant 2 that is installed and is it version 2.0.7? Thanks!

DJI Assistant is usually model specific.  So there is a version for Inspire 2, a different version for Mavic, etc.  The build number for each one could be different for the most recent available.

I had to update a driver called LibUSB-win32 . I downloaded from the Web. There was No exclamation mark on my previous but I re installed this anyway to try and it fixed my issue. I have the Cal button now I go my Mp2 Vision calibrated and no more error!

Hope that Helps!

Hello I have a Mavic 2 Pro and had same issue calibrating the vision sensors with a button Calibrate Greyed out recently. Not only do you need to run windows with Driver Signed disabled, I had to update a driver .

HI have the same problem using ISO,  P

A very common problem that occurs mostly in Windows 10. The system may treat the DJI Assistant 2 as harmful and give you a prompt that looks like this: If you want the temporary fix, you’ll simply have to use the Windows command prompt (CMD) to run the Assistant 2 app,:

1. pressing Windows+X or just right-clicking the Start button. On the Power Users menu, choose “Command Prompt (Admin).
2. Copy the full path of your DJI Assistant program in the command prompt: with ctrl + c and past it with ctrl + p in the command prompt (copy it up until the actual .exe file of the app)https://freefmod.com/
