Hey there, I’ve dealt with this exact frustrating issue after updating SDK components before—let’s get your simulators back up and running step by step:

• Step 1: Fully Remove the Old HAXM Installation
  Since you can’t uninstall it normally, we’ll do a manual cleanup:

  1. Open Android Studio’s SDK Manager, go to the SDK Tools tab. Uncheck Intel x86 Emulator Accelerator (HAXM installer) and click Apply—even if it throws an error, proceed.
  2. Delete the HAXM installation directory manually:
     • Windows: Navigate to C:\Program Files\Intel\HAXM and delete the entire folder
     • Mac: Use Terminal to run sudo rm -rf /usr/local/libexec/haxm
  3. Kill any running HAXM processes:
     • Windows: Open Task Manager, find haxm_service and end the process
     • Mac: Run sudo killall haxm in Terminal

• Step 2: Install a Compatible HAXM Version
  The error says you need at least HAXM v4.x, so let’s get the right version:

  1. Go back to SDK Manager > SDK Tools, check the Show Package Details box in the bottom-right corner.
  2. Expand Intel x86 Emulator Accelerator (HAXM installer), select the latest stable version (v4.0+), then click Apply to install.
  3. If installation fails, check your BIOS settings: Restart your computer, enter BIOS, find the Virtualization Technology (VT-x/AMD-V) option and enable it. Save changes, reboot, and try installing again.

• Step 3: Fix Emulator Configuration
  Old emulator profiles might clash with the updated HAXM:

  1. Open AVD Manager, select your existing emulator, click the pencil icon to edit it.
  2. Scroll down to Show Advanced Settings, under Emulated Performance, set Graphics to Hardware - GLES 2.0 or Automatic.
  3. If that doesn’t work, try creating a brand new AVD for API 27—sometimes old profiles get corrupted after SDK updates.

• Step 4: Verify HAXM is Running
  After installation, confirm HAXM is active:

  • Windows: Open Command Prompt and run sc query haxm_service—you should see a "RUNNING" status
  • Mac: Open Terminal and run kextstat | grep intel—look for the HAXM kernel extension in the output

If you still hit issues, try updating Android Studio to the latest stable release—sometimes mismatched IDE and SDK component versions cause these weird bugs.
