- Also on Windows 7 (32 Bit) the above solution can be tried.
- If these two options are not solving anything or we are running Nox App Player on previous window versions other than mentioned above in two options then we need to check the settings of the Firewall whether it has made access of all programs closed. If yes then access needs to be enabled.
- We need to locate a file whose extension is ‘inf’ under the path C:\Program Files\ Bignox\ BigNox\ M\ RT\ drivers\ XQHDrv and right click on it and thereafter click on install from the pop up. Then Nox needs to be restarted.

Before doing the above we need to check whether our PC is VT-x supported or not. For that a tool can be downloaded from Google called LeoMoon CPU-V which will show whether our PC is VT-x supported and if yes whether it is on or off.

I played pokemon go for 2-3 hours perfectly. No errors popped u. Then I turned of my pc. Next time when I try to open nox then after 50% loading it shows a red “!” sign beside the nox app player name above. And afterward the whole comuter freezes and I have to shut it downs by unplugging. Please reply with a valid solution
Same sh*t for me, i didnt find a solution
installing vmware workstation player 12 worked for me
I have the same problem.
I got the same issue since today, last night I was playing like normal.
I opened the player this morning, ran the game, it got stuck then I quit the player, open it again and I got a BSOD, after that the problem kept appearing.
I have tried everything from disabling anti virus, updating drivers, adding to firewall, install and reinstall, enabling/disabling VT, nothing seems to fix the problem.
I also found out that the App Player runs normaly when I disable VT, but Pokemon Go won’t run without it. If I re-enable VT, Nox completely freezes my system and It requires a hard restart to operate again.
The red ‘!’ has to do with the Virtualization technology, check it in your BIOS, has to be enabled.
Yes i have same problem
I also have the same problem as of now (installed it like 2-4 days ago too).
And my VT is enabled.
so did anyone found the solution? i’m having this same problem too

Stuck 99% on Mac OS Ex elcapitan
How to fix?
Same problem here!
Same!
Same !
same
Same problem here on Mac OS X El Capitan, it takes forever to get on 99% but when it does it get stuck there.
same problem here!!
To get it working on Mac:
1. Download latest VirtualBox and install that over the one comming woith nox.
2.Once Virtual Box installed head over to Finder and browse to Nox App Player.
Right click on it, then select second option “Show Packet Info” (sorry moc Os x not in English so trying my best)
3. Browse to Contents/Frameworks/Mac OS/data/system.
4.Click the nox.ova file (This will make the virtual machine in VirtualBox)
5. In VirtualBox u can confire the virtual machine. I used 64 bit linux insted of the 32 the file made and upped memory to 2GB. Also upped video memory to 128 and checked the 3D options. (No tech specialist so no idea if it helps nox running better)
6. U should see the nox virtual machine ready but not running in VirtualBox.
Now head back to launcher and click nox app player icon to launch nox and it should start the Virtual machine and have Android booting in your nox window instead of the 99% stuck bug.
Hope this helped at least one person and if u have things to add or if i missed something just add it

I use Nox App Player two weeks. I had no problems. But today came out red exclamation mark (!). And the computer restarts automatically. I tried again. Issue not resolved. I see many people have experienced the same problem today. I tried everything written above. The problem continues. As I said, I had no problems for two weeks. But today is broken. I uninstall, I installed again. I am worried about damaging the computer. What do you recommend it?
After I change the graphics to speed(directx) the app restarts, when the app gets to when 100% it opens an empty window of nox app player
It stops as 99% and says “system init timeout, please restart”

The Same problem here,
Last night ive started nox and it opens perfectly but when i opened today,

First of all, disable “Hyper-V” in Windows features.
Secondly, Completely uninstall Nox. (Use uninstall tool or IObit Uninstaller)
Then download the Nox offline installer and run in.
Done you’re good to go.
Note: If you’re PC is not VT-x supported, then you can’t run Nox. Install LeoMoon’s CPU-V to check if you’re device is VT-x supported.

Here’s what fixed it for me:
I had Team Viewer running in the background, so I closed it, the app then loaded perfectly.
I found a simple solution for myself – initially reading all the comments was a long time job, so i focused on what went wrong. I have pasted a lot of files in the shared folder or NOX player in USERS/Nox_share/
I cleared them and it started working
If you are trying to use Nox Player on a laptop that has the lid closed or the display turned off, via a remote connection, it will not work. Nox appears to require the display be turned on to work. Not only will it not load, and just get stuck at 99%, but if it is already running, you will not be able to use any apps or interact with whatever app is currently on screen. Make sure to keep your laptop lid open if you intend to use a remote connection, and also prevent your display from turning off in your power settings. Or connect an external monitor that stays on.
I’m not able to add New Emulator-Android5.1.1 , every time I tried it says “Failed to Unlock!”.
