Registry key Error: Java version has value '1.

Question

While running

sencha app build production

I am getting the following error:

Error: Registry key 'Software\JavaSoft\Java Runtime Environment'\CurrentVersion'

has value '1.8', but '1.7' is required. Error: could not find java.dll Error: Could not find Java SE Runtime Environment.

java -version , command is showing following:

java version "1.8.0_40" Java(TM) SE Runtime Environment (build 1.8.0_40-b26) Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

Not able to find where path is going wrong. Any idea?

----------------------- EDIT ------------------------------------------------

Note: I am using Windows 7 (64 bit).

I have tried uninstalling the sencha touch cmd and reinstalling. But still same error.

I have uninstalled all the java version instances and reinstalled the latest one, Still the problem persist.

Answer 1

1. open regedit
2. go to [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment]
3. change value CurrentVersion from "1.8" to "1.7"

Answer 2

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 & 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;<other path directories>;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:\>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)

Answer 3

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.

Answer 4

You have to define your jdk folder in variable JAVA_HOME, add %JAVA_HOME% to your variable path

Delete or change name of your java.exe, javaw.exe and javaws in your folder system32

execute cmd.exe, java -version now take the new version that you define in JAVA_HOME.

Answer 5

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=<YOUR JDK 7 HOME>
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\<YOUR USER>\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.

Answer 6

The error is explicit ...

Error: Registry key 'Software\JavaSoft\Java Runtime Environment'\CurrentVersion' has value '1.8', but '1.7' is required.

Error: could not find java.dll

Error: Could not find Java SE Runtime Environment.

... you are attempting to use the java.exe 1.7 executable while the HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment > CurrentVersion registry key has the value 1.8.

The recurring theme to proposed solutions is that the error is a configuration error. The error can be solved in various different manners (e.g. reconfiguration of the users environment or removal of java executables with fingers-crossed and hope that there exists another fallback java.exe in the users %PATH% and that the fallback java.exe is the correct executable).

The correct solution depends on what you're trying to achieve: "are you trying to downgrade from jdk-8 to jdk-7? Are trying to upgrade to jdk-8? ..."

Reproduction steps

1. install jdk-7u80-windows-x64.exe

notes:

• the java.exe executable available in the users %PATH% is installed in C:\Windows\System32
• the installation does not update the users %PATH%
• the HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment > CurrentVersion string registry entry is created (among others) with the value 1.7

2. install jdk-8u191-windows-x64.exe

notes:

• the users %PATH% is updated to include C:\Program Files (x86)\Common Files\Oracle\Java\javapath as the first entry
• the the HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment > CurrentVersion string registry entries value is updated to 1.8

3. update the users %PATH% environment variable, remove C:\Program Files (x86)\Common Files\Oracle\Java\javapath

4. in a new command prompt java -version

Error: Registry key 'Software\JavaSoft\Java Runtime Environment'\CurrentVersion' has value '1.8', but '1.7' is required.

Error: could not find java.dll

Error: Could not find Java SE Runtime Environment.

Solution(s)

1. OP's solution https://stackoverflow.com/a/29769311/1423507 is a "fingers-crossed and hope that there exists a fallback java.exe in the users %PATH% and that the fallback executable is correct" approach to the error. Given the reproduction steps, removing the java.exe, javaw.exe and javaws.exe executables from C:\Windows\System32 (only in my case) will result in no longer having any java.exe present in the users %PATH% resulting in the error 'java' is not recognized as an internal or external command, operable program or batch file. which is not so much of a solution.

2. answers https://stackoverflow.com/a/35775493/1423507 and https://stackoverflow.com/a/36516620/1423507 work however you're reverting to using java.exe 1.7 (e.g. update the CurrentVersion registry key's value to match the java.exe version found in the users %PATH%).

3. make surejava.exe 1.8 is the first found in the users %PATH% (how you do that is irrelevant) i.e.:

   • update the users %PATH% to include C:\Program Files (x86)\Common Files\Oracle\Java\javapath first (ensure that the executables in that directory are correct)
   • update the users %PATH% to include the absolute path of your java binaries first (set PATH="C:\Program Files\Java\jre1.8.0_191\bin;%PATH%")
   • set java specific environment variables and update the users %PATH% with them (set JAVA_HOME="C:\Program Files\Java"; set JRE_HOME=%JAVA_HOME%\jre1.8.0_191; set PATH=%JRE_HOME%\bin;%PATH%)
