Bluestacks Could Not Start the Engine – Windows 10 & Mac Fix

I have used Bluestacks Android emulator for a while now. The reason is that I needed access to Android phone applications on my PC. Learning about Bluestacks and using it helped me have the same experience. However, suddenly Bluestacks could not start the engine on my Windows at home and Mac in the office.

Therefore, I sought a solution. To my surprise, the solutions were plenty.

To make the Bluestacks engine to start on Windows 10 and Mac, I had needed to:

  • Use an older Windows version
  • Change the graphics mode
  • Disable anti-virus temporarily
  • Uninstall and reinstall Bluestacks

I will show you in detail how I did this.

Before that, let’s talk about Bluestacks. Moreover, about some of its features.

Understanding the features allows us to know whether this android emulator is compatible with our Windows 10 PC or Mac. 

 What is Bluestacks?

Bluestacks is an Android emulator. Well, an Android emulator makes your Windows 10 or Mac to behave like an Android device. The result is that on the emulator, you get to run any Android application you want to use on your PC—just the same way as on your Android device.

Occasionally, the Bluestacks emulator engine may not start. One reason could be Bluestacks is not compatible with PC. Therefore, let’s quickly look at the minimum requirement required to install Bluestacks.

Bluestacks Recommended Requirements

  • Microsoft Windows and Mac OS
  • Intel and AMD Core Multi-Processor with a single thread(score over 1000)
  • ATI/Nvidia/Intel graphics(score over 450)
  • RAM of 8GB or higher
  • An up to date graphics driver
  • Fusion, Hybrid, or SSD HDD Drives
  • Broadband Internet connection( just reliable internet)

Warning: Do not install BlueStacks App Player if you use a virtual machine like Oracle Virtualbox, VMWare Workstation, or Microsoft Virtual PC.

Well, if your PC meets the above requirements, solving the engine not starting in Bluestack error can be done as below.

1. Use an Older Windows OS version

At one time, my Bluestacks could not start after a Windows update. I learned that a BlueStacks engine might not begin to incase I was using a new windows version. The solution, therefore, might be to go back to the previous Windows OS.

Note; The limited number of days for reverting your Windows 10 to an older version is 10 days. After that, you may need to use another option.

Maybe uninstall and reinstall Bluestacks, I will touch on this later. So how do we revert to the old Windows version?

  • Press hold Windows key and press I (This shortcut opens Settings)
  • Click on Update and Security
Windows 10 Settings Page
Press Windows+I, Click on Update and Security
  • Click on Recovery on your left side
  • Click “Get Started”(Located in the Go back to an earlier build) 
Update and Security Tab Windows 10 PC
Click Recovery, Then Get Started

Note: If the Get Started button is in grey, then you cannot revert to the previous OS version. In case the Get Started button works, then follow the rest of the instructions on your screen.

Once the revert is done, re-open BlueStacks. If it fails to open, try changing the graphics mode. 

Here’s how.

2. Change Bluestacks Graphics Mode

When you install Bluestacks it runs on an OpenGL engine(by default). I changed my graphics mode on one occasion and Bluestacks opened correctly. Tweaking these settings is easy.

1. Open Bluestacks

2. Click on Settings (Gear icon at the top)

BlueStacks Settings Tab
Click on the Settings icon (At the Top)

3. Select Engine on the left panel

4. Choose DirectX

BlueStacks Engine Settings Tab
Select DirectX

5. Then, let’s restart your PC.

Now, verify whether the Stacks engine can starts. Do not restart, try the same engine but change the Core number and implement RAM capacity settings. Click Restart now. Ascertain that Bluestacks start.

If this does not work, then we need to disable the antivirus program on your PC temporarily. Let’s do it.

3. Disable Antivirus Temporarily

Antivirus software is good for PC. If you have software like Avast do not be surprised if your Bluestacks on one occasion do not start. The reason is that Avast tends to see an autonomous Android emulator to pose a threat to PC security. To use your Bluestacks you may just need to temporarily stop antivirus. Here’s how I usually disable my Avast Temporarily.

Note: Do not disable Avast permanently. It is just for a while to check whether your BlueStacks will work with anti-virus disabled.

1. Right Click on Avast icon at the bottom of your screen( On Windows Systems Tray)

Avast on Windows Systems Tray
Right-click on Avast

2. Place cursor on Avast Shield Control the drop-down menu opens

3. Choose”Disable for 10 minutes” or the one-hour option.

Avast Shield Control Page
Choose Disable For 10 Minutes/1 Hour

Note: This leaves your PC vulnerable for a short while. However, you get to check whether Avast prevents your Bluestacks from starting.

4. A popup “Do you want to continue” opens. Choose “Yes”

5. Re-launch your Bluestacks

Pro Tip: Choose a different antivirus software in case BlueStack starts correctly. In case the problem persists, turn your Avast back on. Then, try another solution.

This time let’s try to uninstall and reinstall our Bluestacks.

4. Uninstall and Reinstall Bluestacks

This is usually a last resort when everything fails. This method allows you to avoid any bugs that could be affecting Bluestacks in the background. So how do we go about this?

1. Close Bluestacks

2. Head to its icon, right-click it and click Quit

Another approach: Press Ctrl+ Alt+Del. This takes you to Taskmanager. From the list, choose Bluestacks and click End Task.

3. Once done, hold press Windows key and press R.

4. In the run box, type %Temp%, then press Enter

5. Now press and hold Ctrl and A

6. Now press the Delete key on the keyboard and type Yes to any popups that appear (This action clears your Temp folder)

7. Now Download the BlueStacks Uninstall from BlueStacks’ official site. Run the software. This software removes anything Bluestack related to your PC.

8. Now click Yes or OK.

The uninstall is complete. Now let’s move on to installing Bluestacks.

1. Go to BlueStacks’ official website. Download BlueStacks latest version.

Tip: The installation should be in safe mode. Therefore we need to Safe Boot.

2. Hold Press Windows+R (This opens the run box)

3. Type “msconfig” and press Enter. Choose Boot
