Hello, like most I spent a long time mindlessly troubleshooting ways to get an Android Screen to mirror with my Nexus 7 2013 Tablet without rooting my device. In fact, I got to a point where I was so completely frustrated that I was determined to root my phone just to get AirDroid to mirror my device on my Windows 7 Desktop. After about 6 hours of mindless trying to get the device to root, AirDroid randomly Airmirrored my tablet. I can't guarantee this process will work for you although here is what I learned. My Fallout Shelter minions have never been happier!
WugFreshDevelopment: Nexus Root Toolkit (

It's important to note that this is used because it walks you through every step necessary to get the drivers installed correctly without actually rooting your device. It will also show you how to uninstall drivers affecting activation.
Specification:
Device: Asus Nexus 7 2013 Tablet
Build number: MOB30M
Android Operating System: 6.0.1
System Status: Non-rooted
BOX: Windows 7 Pro x64 Sp1
Necessary tools:
A micro USB cord
A avaliable USB port on BOX
Some patience or determination to make this work
Procedure:
Before proceeding, if you are using a desktop with front USB and back USB ports, I recommend using a back USB port.
Follow the steps as recommended in the Nexus Root Toolkit guide above for Full Driver Installation Guide - Automatic + Manual
Step 1: Uninstall the previous drivers as recommended (it will launch a tool to make this easy for you to identify and remove)
Step 2: Do this step if you can. I still don't have my Nexus 7 visable through devices and I can AirMirror just fine.
Step 3: Driver Solution #1 worked for my box; as a general rule I usually do not install drivers while my device is connected.
Step 4: Run Full Driver Test; this step should complete.
TIP #1: Sometimes you need to access Settings --> Developer options --> USB Debugging on/off or Settings --> Developer options --> Select USB Configuration --> Charging/MTP/RNDIS (USB Ethernet).
TIP #2: Whenever you change the USB configuration make sure to wait for the drivers to detect the change; it does this through Windows Update so you may need to wait a while.
The Catch:
Android device --> Settings --> Accessibility --> AirDroid Notification Mirror service --> On
Android device --> Settings --> Developer Options --> Select USB Configuration --> RNDIS (USB Ethernet)
When the android device asks for authorization "Allow USB debugging? The computer's RSA key fingerprint is: ...", Click OK
Do Not check "Always allow from this computer." Doing so usually prevents this trick from engaging AirMirror to Activate.
NOTE: If you are still having trouble connecting or your device can not be found, try installing the Android Studio
