The emulator NoxPlayer has long established itself as one of the most stable tools for running mobile applications on a personal computer. However, like any complex software, it requires regular maintenance to work correctly with modern games and applications. Users are often faced with confusion: whether it is necessary to update the app shell itself or whether it is necessary to change the version of the operating system Android inside the virtual machine. Understanding this difference is critical for data preservation and performance improvement.
The upgrade process can concern two different levels: updating the emulator client software to the latest developer build or changing the Android kernel (for example, moving from Android 5 to Android 7 or Android 9). Each of these processes has its own technical features, risks and requirements for the system resources of your PC. In this guide, we will analyze both scenarios in detail so that you can choose the optimal upgrade path without losing progress in games.
It is worth considering that some older versions of the emulator may not support the automatic search for updates function due to changes in the developers' server policy. In such cases, manually downloading the installer becomes the only correct solution. In addition, switching to a newer version of Android inside the emulator often requires creating a new instance of the system, which implies the need to first back up important data.
The difference between updating the app and the Android version
Before proceeding with technical manipulations, it is necessary to clearly distinguish between the concepts. Updating itself NoxPlayer is installing a new version of the executable file that controls the virtual machine. This action usually brings bug fixes, optimization of RAM consumption and support for new interface features. This procedure is as safe as possible and rarely leads to loss of user data.
On the other hand, changing the Android (kernel) version inside the emulator is a more complex operation. Essentially, you are creating a new virtual machine with a different operating system. The old instance with Android 5.1.1 may remain on the disk, but you will launch a new container with Android 7 or Android 9. This is necessary if a particular game requires a more recent version of the OS to run anti-cheat or for graphics to work correctly.
⚠️ Attention: Changing the Android kernel (for example, from 5 to 7) in most cases requires creating a new instance. Data from the old instance is not transferred automatically, so make a backup of applications using built-in tools or third-party utilities before starting the process.
Developers often release security and optimization patches specifically for the emulator shell, while ignoring the internal version of Android in already created instances. Therefore, regular updating of the client part Nox is a mandatory procedure to maintain stability. If your application simply refuses to start (refuses to start) due to a mismatch with the OS version, then intervention in the kernel settings is already required.
Automatic update of the client part NoxPlayer
The easiest way to keep the emulator up to date is to use the built-in update mechanism. In the latest versions of the interface, this function has been moved to a convenient settings menu. The system independently checks developer servers for new builds and prompts the user to download them. This method is suitable for most users who just want to get the latest fixes.
To start the procedure, you need to open the emulator settings. This is usually done through the gear icon in the upper right corner of the app window or through the menu Menu → Settings. In the window that opens, go to the General (General) tab. This is where the block responsible for checking versions and automatically downloading updates when they appear is located.
If the automatic check does not work or gives a connection error, you can use the manual check button. Sometimes servers can be overloaded, especially on days when major updates are released for popular games. In this case, you should wait a few hours and try again. Make sure that your antivirus or firewall is not blocking the emulator's connection to external resources.
If the update button is grayed out, try running NoxPlayer as an administrator. This often solves problems with access rights to system files when downloading updates.
After downloading the installation file, the system will prompt you to restart the emulator to apply the changes. This process takes from 2 to 5 minutes depending on the speed of your hard drive. During the reboot, do not try to forcefully close the installation window, as this may damage the configuration files and make it impossible to launch the app in the future.
Manually installing a new version of the emulator
In situations where the built-in updater gives an error or the version on the server seems more stable to you than what is automatically suggested, it makes sense to perform a manual installation. This method is also relevant if you are reinstalling Windows or transferring the emulator to another computer. The manual approach gives complete control over which build will be installed on your machine.
The first step is to visit the official website of the developer. It is extremely important to download distributions only from trusted sources to avoid introducing malicious code. The main page usually contains the latest stable version. For advanced users, beta versions are also available, which contain experimental features, but may be unstable.
The process of installing a new version over the old one is usually seamless. The installer automatically detects the path to your current installation and prompts you to update the files, while preserving all Android instances you've created and installed applications. However, before running the installer .exe file, it is recommended to completely close the emulator process through the task manager.
- 📥 Download the current installer from the official developer resource.
- 🛑 Completely shut down the emulator through the system tray and task manager.
- ⚙️ Run the installer and follow the instructions of the installation wizard without changing the default path.
- 🔄 After completion, click "Finish" and run the updated app.
Sometimes after a manual update, the interface may look different or some settings may be reset to default values. This is normal behavior when changing major software versions. You will need to re-adjust resource allocation (the number of processor cores and the amount of allocated RAM) in accordance with the capabilities of your hardware.
☑️ Checklist before updating
Changing the Android kernel version inside the emulator
Many users are looking for a way to “update Android” inside a working instance, similar to how this is done on physical smartphones through OTA updates. In the emulation environment NoxPlayer this process is implemented differently. You can't just click the "Update system" button inside Android settings to upgrade from version 5 to version 7. Instead, an instance management system (Multi-Drive) is used.
To change the kernel version, you must use the utility Nox Multi-Drive Manager. This app is installed along with the main emulator and allows you to create, copy and delete virtual machines. This is where you can select the desired version of Android for the new window you create. This gives you flexibility: you can simultaneously have one instance for older games and another for new, demanding projects. The process of creating a new instance with a different OS version is as follows. Launch the icon Android 5 for old games and other with Android 9 for new demanding projects.
The process of creating a new instance with a different OS version is as follows. Launch icon Multi-Drive on the desktop. In the window that opens, click the Add an emulator (Add Emulator) button. In the selection menu that appears, you will see the available Android versions. Select the one you need, for example Android 7 64-bitif your game requires this particular architecture.
⚠️ Attention: The new copy will be absolutely clean. It will not contain your saves, Google accounts, or installed applications. You will have to configure it from scratch or try to transfer data manually if the game supports cloud saves.
After selecting the version, the system will begin the process of cloning or creating a new virtual machine. This may take from 3 to 10 minutes depending on the speed of your drive. SSD significantly speeds up this process compared to traditional HDDs. Upon completion, a new window will appear in the list, which can be launched by double-clicking.
Why is there no Android update button inside the settings?
The emulator architecture is built on isolated containers. Each Android kernel is a separate disk image. Updating on the fly could lead to critical library compatibility errors, so the developers chose the path of creating new instances.
Performance tuning for newer versions
Newer versions of Android, such as Android 7 or Android 9, require more computing resources to run smoothly. If after creating a new instance you experience a drop in FPS or interface sluggishness, you need to adjust your performance settings. The standard settings that were suitable for Android 5may not be enough for modern kernels.
Go to the settings of the new instance and pay attention to the Performancesection. For versions of Android 7 and higher, it is recommended to allocate at least 2 processor cores and 4096 MB of RAM. If your PC has the resources to spare, you can increase these values to 4 cores and 8 GB RAM, which will ensure maximum smoothness in heavy 3D games.
| Android version | Min. CPU cores | Min. RAM volume | Compatibility mode |
|---|---|---|---|
| Android 5.1.1 | 1 core | 2048 MB | DirectX / OpenGL |
| Android 7 (32-bit) | 2 cores | 4096 MB | OpenGL+ |
| Android 7 (64-bit) | 2 cores | 4096 MB | OpenGL+ / DirectX |
| Android 9 (Pie) | 4 cores | 8192 MB | OpenGL+ (Recommended) |
It is also important to select the correct graphics rendering mode. For most modern games on the new Android cores, the optimal choice is the OpenGL+mode. However, if you encounter a black screen or artifacts, try switching to DirectX. This option is located in the graphics section of the settings and requires a reboot of the emulator to take effect.
New versions of Android (7 and 9) require that VT virtualization be enabled in the BIOS. Without this technology, the emulator will work extremely slowly or will not start at all.
Solving common problems when updating
During the updating process, users may encounter a number of technical difficulties. One of the most common problems is an error downloading updates or freezing at the file verification stage. This is often due to the connection being blocked by the provider or antivirus software. In this case, you should temporarily disable protection or add the emulator to exceptions.
Another common situation is a “cyclic reboot” after updating the Android kernel. If the new instance constantly reboots and does not reach the desktop, try clearing the emulator cache through the Multi-Drive menu. Also make sure that your video card drivers are updated to the latest version, as older drivers may not work correctly with new rendering instructions.
If after the update all game icons disappeared or the settings were reset, check whether you are running the same instance. It's easy to confuse windows when using Multi-Drive, especially if they have the same name. Rename your virtual machines in the manager to clearly understand which version of Android is installed. This will save you time in the future.
⚠️ Attention: The interface and menu layout may vary slightly depending on the specific version of NoxPlayer. Developers periodically change the design, so focus on the essence of the actions, and not just the appearance of the buttons.
Frequently asked questions (FAQ)
Is it possible to update Android inside the emulator without creating a new window?
Unfortunately, no. The NoxPlayer architecture does not support OTA kernel updates within an existing instance. To switch to a new version of Android, you need to create a new instance through the Multi-Drive Manager utility and configure it again.
Will my saves be in games after updating the emulator?
When updating the client part of the app (shell), the data is saved. However, if you create a new instance with a different version of Android, the data is not automatically transferred. Use the account linking function (Google Play, Facebook) in the game itself to restore progress in a new window.
Why does the emulator write "Error checking for updates"?
This may be caused by problems with the Internet connection, blocking of the emulator servers by an antivirus, or an outdated version that is no longer supported by the update server. Try manually installing the latest version from the official website.
Which version of Android is better for games: 5, 7 or 9?
For most modern heavy games, it is recommended Android 7 64-bit or Android 9. They provide better compatibility with new graphics libraries and anti-cheats. Version Android 5 is only suitable for very old or undemanding applications.
Do you need to remove the old version before installing the new one?
No, the NoxPlayer installer can update over the previous version, saving settings and data. Removal is required only if the current installation is damaged and cannot be restored.
