PANIC: Missing emulator engine program for 'arm' CPUS. in Android studio

Question

Before some time everything was working fine, But now when I launch emulator I am getting error as

PANIC: Missing emulator engine program for 'arm' CPUS.

Here is screen shot

I had tried to update sdk manager, But there is nothing to update.

In extras everything is installed, But I think there is something missing in this package, But I don't know how to install that one. Any suggestion will be appreciated. Thanks in advance.

After clicking on help menu and check for updates I got message as You already have updated version as shown in image below

I also uninstall android sdk tools and reinstall it but still no luck

Answer 1

I answered this in another post.

In my case, my PATH environment variable was set incorrectly. It was including

/sdk/tools

Instead of

/sdk/emulator

emulator.exe exists in both of these directories, so the emulator command will work either way. However, emulator-arm.exe only exists in my emulator directory.

Answer 2

Avast Antivirus is sensing emulator-arm.exe as a threat and blocking from some reasons. When you add it to exclusions in Virus Chest page with right-click -> "restore and add to exclusions" it's not solved in future runnings. To solve this permanently in Avast 2015 :

Settings ->

Active Protection ->

File System Shield ->

Customize ->

Exclusions then add threat as a exclusion . And then press ok.

Answer 3

I had the same problem. Avast was blocking the files as @JakeM stated. After following what @PPD stated its working fine. Even when Avast is turned on. Not much of an answer but hope it helps.

Answer 4

I have had this problem in Eclipse. It looks like Avast thinks it is infected with Win32:Dropper-gen.

Answer 5

Hi Guys after JakeM and Hnkonan response to my question I got answer to my question. First of all thanks to both.

The main reason was Avast antivirus. First of all I had disable avast after that I had open Virsu chest of it and I got there emulator-arm.exe file. I had restore it. After that I restart android studio. But at this time it giving me error as

Android-Studio : Error: Could not create the Java Virtual Machine

I had downloaded notepad++ then open android studio/bin folder in this bin folder there is one file name as studio.exe.vmoptions. Open this file file using notepad++ and change the -Xms128m to -Xms512m and restarted Android Studio.

After that I am able to launch emulator. Currently my Avast is disable but it may possible after enabling it will again move emulator-arm.exe file to virus chest. Thanks guys

Answer 6

Had the same problem but here PANIC: Missing emulator engine program for 'arm' CPUS was helpful information

For some reasons Avast antivirus has considered emulator-arm as virus and put it to quarantine. And continues to do that. Check please if You have that AV soft

It started near hour-two ago so can be related to new "viruses definitions" of Avast that somewhy quarantines that files

Answer 7

It is a problem with emulator-arm.exe in tools directory of sdk. Copy it from install package and everything will be OK
