Do you have JAVA_HOME in your system environment variables?

JAVA_HOME=C:/Program Files/Java/jdk1.8.0_11

Yes. I have JAVA_HOME – Ko Kyin Shein Jun 03 '15 at 08:59
In my case, set JAVA_HOME to jdk8 is not enough, the `PATH` must be updated also, `set PATH=%JAVA_HOME%\bin;%PATH%` – alijandro Jan 11 '23 at 02:08

Run android studio as administrator. It will definitely work. No need to reinstall neither android studio nor java.

In my case, after upgrading Android Studio 3.1.2, I tried open C:\Users\yourUserName\AppData\Local\Android\Sdk\tools\monitor, Windows alert "can't find 'lib\monitor-location'. Make sure you typed the name correctly, and then try again". Then I tried open tools\lib\monitor-x86_64\monitor, it works!

For some reason I had a problem running it (registry perhaps). Had to download JRE from : https://filehippo.com/search?q=jre . Now it works fine when opening the file that you've provided. – android developer Apr 27 '19 at 18:04

I'm on Windows and open Android Studio in Administrative Mode (Run as administrator). Worked for me.

I had the same problem, i solved it using jPortable, if you're using Windows then take this one, there are two versions 32bits and 64bits : https://portableapps.com/apps/utilities/java_portable
I changed the location for the extraction from C:\SDK\tools\lib\monitor-x86_64\CommonFiles\Java64 to C:\SDK\tools\lib\monitor-x86_64\jre and it worked.

You need to set path to your ..jre\bin location :

Check in: File > Project Structure your JDK location
add the \bin there , my path is : C:\Program Files\Android\Android Studio\jre\bin
set the path in your Environment Variables, for WINDOWS 7 :
- the From the desktop, right click the Computer icon.
- Choose Properties from the context menu.
- Click the Advanced system settings link.
- Click Environment Variables
- New System Variable
- set the path the following way :

Variable name: Path

Variable value: your path

in my case: Variable value: C:\Program Files\Android\Android Studio\jre\bin

Now you can start the Monitor.exe, my location is here : C:\Users\Admin\AppData\Local\Android\Sdk\tools\lib\monitor-x86_64

for WIN7 32bit start the Monitor.exe from ...Android\Sdk\tools\lib\monitor-x86

Make sure have installed JDK7 or JDK8 depending on your OS bits If you are using 32bits your install JDK7 or 8 of 32bits After you install JDK, your JAVA_HOME in your system will be located in

C:\Program Files\Java\jdk1.8.0_40

To check if your JAVA_HOME is set, CLICK Start Menu > Computer > Right Click on Computer > Properties > Control Panel Home will appear, > click Advanced System Settings, under > Advanced Tab click > Environment Variables and check on the > System Variables for > Path if Java [C:\ProgramData\Oracle\Java\javapath;] is there, than you are good to go.

Make sure you have your JAVA_HOME in your system environment variables.

Hope this well help you. If it helped you, please mark it, so that it can the useful to others.

Do you have jdk1.8.0_40 32bits installed on your PC? – King Jun 04 '15 at 07:00

Please ensure you have Android SDK Tools installed. I had a fresh copy of Android Studio and kept getting this error.

To install:

Tools -> Android -> SDK Manager -> SDK Tools (tab) -> Tick Android SDK Tools x.x.x (if it's not installed) -> Apply

Once installed / finished, try restarting Android Studio then selecting Android Device Monitor from the Tools drop down again.
