🛠️ Android Emulator Crash FIX — StartService FAILED with error 4294967201

❗ Problem

When launching the Android Emulator, I kept getting this vague and frustrating error:

Running Android Emulator hypervisor driver installer
[SC] StartService FAILED with error 4294967201
The emulator process for AVD <device> has terminated.

I spent hours:

• Enabling virtualization (VT-x / VT-d / SVM)
• Disabling Hyper-V
• Running PowerShell commands like Disable-WindowsOptionalFeature
• Adjusting TPM and BIOS settings
• Trying PsExec, checking SeLoadDriverPrivilege, etc.

📌 And the actual cause? None of that was the problem.

✅ The Real Fix

After finally checking the emulator logs (in idea.log), I saw errors pointing to missing DLLs, such as:

vcruntime140.dll not found  
msvcp140.dll is missing  

💥 The emulator was silently failing because the required Microsoft Visual C++ Redistributables were missing on my system.

🔧 Solution

Install the latest Visual C++ Redistributables from Microsoft:

• VC_redist.x64.exe
• VC_redist.x86.exe

After installing both versions, reboot your PC.

✅ Once I did this, the emulator launched with no issues.

🗣️ Final Advice

Before diving deep into BIOS, disabling security features, or giving yourself a headache over Hyper-V:

👉 Check the Android Emulator logs first (idea.log, logcat, or the emulator command output).

They're often much smarter than the error messages you see on screen — and they’ll save you hours.

Hope this helps someone avoid wasting time like I did. 🙃
