aribeiro answer has worked for me - with minor changes   I Removed the reference to C  ProgramData Oracle Java javapath  from the Path environment variable I made  path to jdkhome as the first entry in my PATH environment variable  I think this alone is all that is needed

My solution for this problem came after reading and trying all of the above   In my case I tried to downgrade Java to use printouts in Apache ActiveMQ  After uninstalling all Java versions and cleaning the registry I was getting the same error     Error  Registry key  Software JavaSoft Java Runtime Environment  CurrentVersion    has value  1 7   but  1 8  is required     In my case I needed to go to environment variables  edit path  open the javapath location  C  ProgramData Oracle Java javapath  and there it was - three files  java exe  javaw exe  javaws exe  that remained from the JRE8 version     After establishing this fact I simply switched them with the same files from C  Windows SysWOW64 directory  those were from the JRE7 version  and it all worked perfectly

Please change JAVA BIN and JAVA HOME system variable  and then restart system or maybe relogin  You are having that error because it is still jdk1 7 path  On windows it is like this

First you should have Java 7  If you don t have  install it first  I don t know what you are using  Linux  Mac  yum  apt  homebrew  you should find out yourself    If you already have Java 7  run   echo  JAVA HOME   Output should be something like this  usr lib jvm java-8-oracle  Near this directory  you should see java-7 directory  After you found it  run   export JAVA HOME   java-7-dir    Change  java-7-dir  with your directory path  Then you can run your command   This is only a temporary solution  To change it permanently  put the above command to your    bashrc file   EDIT  If you are using Windows  change environment variable of JAVA HOME to your Java 7 installation directory path

I ve had the same problem  Simple solution that worked for me is to rearrange the entries in the PATH for JRE JDK  This problem started to appear after installing JRE 8 whose installation has put some executable files in System32 or SysWOW64 directories  these executable files are messing up  To resolve the problem    Create environment variable pointing to JDK home as JAVA HOME   set JAVA HOME C  Progra 1 Java jdk1 8 0 45 Put the entry  JAVA HOME  bin at start in your PATH environment variable  Appending existing value of PATH  For example    path C  Program Files Java jdk1 8 0 45 bin  path

re  Windows users  No  Don t remove the Javapath environment reference from your PATH variable   The reason why the registry didn t work is that the Oracle Javapath script needs to run in the PATH sequence ahead of the JRE  amp  JDK directories - it will sort out the current version   put this directory at the HEAD of your  PATH  variable   C  ProgramData Oracle Java javapath    or wherever it is on your desktop   so your PATH will look something like this - mine for example  PATH C  ProgramData Oracle Java javapath  lt other path directories gt  E  Program Files Java jdk1 8 0 77 bin E  Program Files Java jre1 8 0 77 bin   You will then see the correct  current version   C   gt java -version java version  1 8 0 77  Java TM  SE Runtime Environment  build 1 8 0 77-b03  Java HotSpot TM  64-Bit Server VM  build 25 77-b03  mixed mode

One possible solution to this problem is to add at Sencha CMD folder a bat file as sugested at this thread Sencha Cmd 5   Java 8 Error   The batch will have the name  sencha bat  with this code    echo off set JAVA HOME  lt YOUR JDK 7 HOME gt  set PATH  JAVA HOME  bin  PATH  set SENCHA HOME   dp0 java -jar   SENCHA HOME  sencha jar       Place it at sencha folder  in my case is  C  Users  lt YOUR USER gt  bin Sencha Architect Cmd 6 2 0 103   The following step is to change PATHEXT enviroment varible  Change at user variables to have the least impact possible   I change from  COM  CMD  EXE  BAT  VBS  VBE  JS  JSE  WSF  WSH  MSC   to  COM  BAT  EXE  CMD  VBS  VBE  JS  JSE  WSF  WSH  MSC   The idea is to make windows run  bat files first than  exe files  This is important because in sencha folder there is already an  sencha exe  file  And in the command line if you type  sencha  it will execute  sencha exe  instead of  sencha bat    This was the only solution that worked for because I m very restricted when it comes to permissions
