Android Studio installation on Windows 7 fails no JDK found

Question

I downloaded Android Studio and attempted to launch the program   This is running on Windows 7 64-bit with Java 1 7  During the installation my Java 1 7 is detected  and the rest of the installation goes through just fine  However  when attempting to launch the application from the desktop icon  nothing happens  Looking at the task manager  a new process from the CMD is loaded  This is because it s attempting to run the batch file studio bat   When I execute via CMD  I get the following error      ERROR  cannot start Android Studio  No JDK found  Please validate   either ANDROID STUDIO JDK  or JDK HOME or JAVA HOME points to valid   JDK installation  ECHO is off  Press any key to continue         I ve attempted to open the idea properties file to see if there was something I could configure for this ANDROID STUDIO JDK or something like that  However  I found nothing  I hope some of you can let me know if you were able to install this or if you are having problems as well

I ve tried so many of the answers here but none of them works  so I decided to mix some of the answers here and I am successful     Step 1  Go to the system properties by right-clicking on My Computer or by pressing windows button on typing This PC and right clicking on it and selecting Properties     Step 2  Click the advanced system settings or Environment Variables  Step 3  Take note that there are 2 different variable  What you need to create is system variables not user variables  when you clicked new type the following  Variable name  JAVA HOME  Variable value  C  Program Files Java jdk1 8 0 25   Note  Please check if the path is right  sometimes it is C  Program Files  x86  Java jdk1 8 0 25   Step 4  Run the android studio  no need to restart   Note    C  Program Files Java jdk1 8 0 25  depends entirely on the installation path of your JDK not JRE so don t be confused if you see something like the picture below  Just enter the location of your jdk  in my case it is C  Program Files Java jdk1 8 0 25     Do not include the bin folder when you enter the Variable value       Edit  For Windows 8 and 10 Users   Try to run C  Program Files Android Android Studio bin studio exe instead of C  Program Files Android Android Studio binstudio64 exe

Sometimes you can resolve this type of issue by setting environment variables so the process looks for the JDK in the right spot   Another approach is to figure out where the process is looking  then put your JDK there   I ve had lots of success using Process Monitor from Sysinternals    Start -  Run -  procmon Go to the Filter menu  then select Filter    Set Event Class is File System then Include Add  then OK   This will filter down to all the file system operations taking place on your machine   You could try filtering based on the result of the File System operation    Right click on the Result column  then Exclude  SUCCESS    You can also quite easily filter based on the process name  either from the Filter    menu option or by right clicking on the Process Name column and selecting Include  process exe    Once you find the file system operation that s failing  the Path column will tell you where to put your JDK   I ve found this to be very empowering  Especially compared to the frustrating process of changing environment variables by trial and error

I couldn t get this to work no matter which environment variables I set  So I simply put a copy of the JDK into my Android Studio installation folder    Copy the contents of the JDK installation  for example  C  Program Files  x86  Java jdk1 7 0 21  Paste them into the installation directory of the Android Studio  for example  C  Program Files  x86  Android android-studio    I somewhat assumed that the issue was caused by having the x64 version of the JDK installed  But what was especially confusing was the fact that I could start Android Studio just fine when I started the studio bat as an Administrator  even though the environment variables were set for my personal user account    studio bat will look for several valid options when determining which JDK to use         Locate a JDK installation directory which will be used to run the IDE       Try  in order   ANDROID STUDIO JDK     jre  JDK HOME  JAVA HOME    As explained above  I picked the    jre option

If setting the JAVA HOME variable doesn t work for you  set   STUDIO JDK C  Progra 1 Java jdk1 8 0 172   Where the path points to your JDK installation This is the only thing which works for me in Windows 32bit with Android 10 and up

MAKE SURE YOU RESTART ANDROID STUDIO  Even though i should know better and swear i did  make sure you restart studio after making these changes as it clearly does not check them on every build  which to me makes sense that system user variables should only be read once on startup   Anyway  yea    Make sure you restart after you make these changes    Path   to the bin folder in the jdk folder  path already exists   JAVA HOME   to the jdk folder

OK  I figured out how fix this nasty bug   Before you start  Go to your Android Studio installation folder and locate the bin folder  Inside the bin folder  you will find studio bat  Execute the file  and it ll show the error  If it is about the Java path then follow the tip 1   Tip 1  When you set the path JAVA HOME  etc   make sure not to include bin at the end of the path  This solved the issue for me   JAVA HOME    C  Program Files Java jdk1 7 0 21  path    C  Program Files Java jdk1 7 0 21 bin  It works fine with JDK 1 7  I tried with 32 bit    If you do so  you can see the initial screen as below     Tip 2  Are you getting the below error message      Your Android SDK is out of date or is missing templates  Please ensure   you are using SDK version 22 or later    This error probably occurs  because you have reference to your older SDK  that you downloaded with Eclipse  in your path variable  Go to Environment variables and remove any reference to the old SDK folder and point it to new SDK folder that is found inside the Android Studio installation folder   Save and restart Studio  things should work as expected now    Tip 3  If you hate messing around with the path variable as given above by removing old references  simply follow the following steps to refer to new SDK path that comes with Studio    Project Defaults  - gt   Project Structure  - gt  Click  New  - gt  Select  Android SDK  - gt  Select the SDK folder inside the studio installation
