How To Fix Bluestacks Engine Won’t Start

As previously said, there are various reasons why the Bluestacks engine may fail to start. As a result, there is no one-size-fits-all solution, and each user/computer will require a unique solution.

Try temporarily stopping your antivirus software before moving on to more complex methods (Windows Defender by default). Every third-party application, particularly Bluestacks, is constantly monitored by antivirus software, resulting in software conflicts that might degrade the application’s performance and cause various problems.

Each antivirus application has its technique for disabling it. Most, though, may be disabled by right-clicking on their system tray icons and selecting the appropriate options. Switch to another antivirus program or add Bluestacks to its exception list if disabling your antivirus solves the problem. Alternatively, we have five additional options for you to consider.

Method 1:  Switch To DirectX And Increase The Number Of CPU Cores & Allocated RAM

Bluestacks is essentially a game emulator for Android. As a result, changing the graphics mode is a quick remedy for the Engine not starting issue. Bluestacks runs on OpenGL by default. However, it can alternatively operate on DirectX.


The swap option is available in Bluestacks’ options.

If changing the graphic mode doesn’t work, you can always increase the number of CPU cores, and RAM allocated to Bluestacks to boost performance.

Increase The Number Of CPU Cores

  1. Open Bluestacks by double-clicking on its desktop shortcut icon or using the Windows search bar (Windows key + S) to look for it. If the problem notice “Bluestacks engine won’t start” appears again, simply disregard it for the time being.
  2. In the top-right corner of the application window, click the Bluestacks Menu button (three horizontal dashes or a downward-facing arrow capped with a horizontal dash in specific prior versions) (next to the resize window and close buttons).
  3. Select Settings from the drop-down menu that appears.

4. Click the option on the left side of the Settings window to switch to the Engine settings pane.

5. Select DirectX from the Graphics Renderer drop-down menu.

6. At the top of the screen, you’ll see a notification that says ‘Checking DirectX compatibility,’ followed by another message, ‘ Restart Bluestacks to boot in DirectX.’

7. Click the Save button first, then the ‘Restart Now’ button in the following dialogue box.

select directx and click on restart now

Bluestacks will now open using DirectX, perhaps resolving the issue you’ve been seeing. If switching to DirectX graphics mode doesn’t work, try increasing the number of processors and RAM that Bluestacks has access to. Switch to DirectX and repeat steps 1 to 5 of the approach as mentioned earlier. If the RAM (MB) slider isn’t set to the ‘Recommended Memory’ value by default, increase it before hitting the Save button. After that, click Save, then Restart Now.

Method 2: Run Bluestacks In Compatibility Mode & Grant Complete Security Access

It’s also possible that Bluestacks lacks the security clearance required to run on your machine. The security settings may have changed due to the most recent Windows or application upgrade. To give Bluestacks complete control, do the following:

  1. Right-click on the Bluestacks desktop shortcut icon from the context menu and select Open file location. If you don’t see a shortcut icon for BlueStacks Client, go to C: ProgramDataBlueStacksClient in File Explorer.
  2. Right-click the Bluestacks.exe file and select Properties from the context menu. (Alternatively, left-click the file and hit Alt + Enter).

3. Go to the Properties window’s Security tab and click the Edit button next to it. Then, click Edit to alter permissions.

4. First, select your username from the list of users presented under group or user names, and then check the box in the Allow column for Full Control under Permissions for *username*.

5. To preserve your changes, click Apply, and then OK to depart. Check if you can resolve the Bluestacks engine won’t start issue.


If not, you can try running Bluestacks in compatibility mode for a different Windows version if you’ve only recently upgraded to Windows 10. To do so, follow these steps:

  1. Select Properties from the right-click menu on the Bluestacks shortcut icon.
  2. Select ‘Run this program in compatibility mode for.’ from the drop-down menu. The compatibility tab is where you’ll find it.


3. To run Bluestacks in compatibility mode, select an appropriate Windows version and click Apply, then OK.

Method 3: Turn On Virtualization To Start Bluestacks Engine

At its core, Bluestacks is a virtualization program. Virtualization technology is built into some Intel and AMD chipsets, which enhances speed when virtualizing software like Bluestacks is utilized.


The technology aids in the easy and stress-free use of such software. Moreover, some users have reported that enabling Virtualization solves the Bluestacks engine won’t start the problem. Although not all systems have the technology, you should check to see if yours has before proceeding with this procedure.

To see if your Intel system supports Virtualization, go to:

  1. Go to the next page. In your selected web browser, open Intel® Processor Identification Utility and click the Download button on the left side (under Available Downloads). Depending on your internet speed, you can download the file in a few seconds or minutes.


2. To install Intel Processor Identification Utility on your computer, double-click the installation file. After that, follow the on-screen prompts/instructions.

3. Once the Utility application is installed, open it and click the + symbol to expand the CPU technologies area. (A user account control will display at the time of launch, asking for permission to allow the application to make changes to your system.) To continue, select Yesintel virtualization technology

Look for Intel® Virtualization Technology in the CPU technologies list (usually the first item). There will be a resounding check to the left of your system if it supports the technology (or a yes next to it).

AMD system supports Virtualization

To see if your AMD system supports Virtualization, do the following:

  1. Go to the next page. Use your chosen browser to download the required file and search for AMD Virtualization Technology and Microsoft Hyper-V System Compatibility Check Utility.
  2. Double-click the.exe file you just downloaded and followed the on-screen directions to install it.

check if your amd system is compatible with virtualization

3. Run the application to see if your computer can run virtualization software. If it does, you’ll see the following message: “The system is Hyper-V compatible.”

Follow the instructions below to enable Virtualization technology on your Intel or AMD machine. If not, move on to the following method.

  1. You can enable Virtualization from the BIOS menu, but you’ll need to restart/reboot your computer to do so.
  2. Hit the Windows key on your keyboard, press the Start button to access the Power menu, and then pick Restart.

3. When your computer maker’s logo appears, press Esc, Del, F12, F10, or F8 several times to enter BIOS. Because each manufacturer’s BIOS key is different, check the documents that came with your computer or do a quick Google search for your BIOS key.

enter setup

4. Using the arrow keys, navigate to Virtualization Technology, Intel Virtualization Technology, Intel VT for Direct I/O, or any other similar option and hit enter to enable it.

5. Exit BIOS after saving your changes. The computer will restart automatically. Once it does, check to see if the Bluestacks engine won’t start issue has been resolved.

Method 4: Revert Back To A Previous Windows Version

A new Windows update may be incompatible with Bluestacks, resulting in the engine not starting. Try to remember if the problem began after installing a recent Windows update. If it did, you have two options: wait for Microsoft to release a new update and hope it fixes the problem, or revert to a previous version that didn’t cause the engine startup error.

click on update and security

  1. Click the start button, then the cogwheel symbol to open Windows Settings. (Alternatively, use Windows key + I to get straight to the settings menu.)
  2. Select Update & Security from the drop-down menu.
  3. In the left panel, look for Recovery settings and click on it.

go to recovery

4. In the ‘Go back to the prior version of Windows 10’ section, click the Get Started option. To roll back to a prior build of the OS, follow the on-screen instructions.

If you haven’t updated Windows in more than ten days, the Get Start button will be greyed out, and you won’t be able to reverse back. The only thing you can do now is waiting for a new update to be release.
