System Configuration:
OS - Windows 8
System type - 64-bit Operating System , x64-based processor
I have installed java-8 and set JAVA_HOME as
C:\Program Files\Java\jdk1.8.0
I am getting error as below image while Tizen-sdk-for-wearable-setup Installation.
error - Cannot execute Java even if it was installed. Check environment variable or Java version(over 1.6) please.
I tried installing after JDK 7 both 32 bit and 64 bit and setting JAVA_HOME - Program Files path and Program Files (x86) path both also it didn't worked.
I have a another system in which the Issue didn't occurred.
System Configuration :
OS - Windows 7 Enterprise
System Type - 32 bit operating system.
Installed Java - C:\Program Files\Java\jdk1.6.0_45
JAVA_HOME set as - C:\Progra~1\Java\jdk1.6.0_45
Now there may be many chances why installation is not getting in my win-8 64 bit.
64 bit JAVA support is not available.
I am not sure about ~ symbol in JAVA_HOME path but it may be to escape space between Program Files and I have not set java home using this symbol.
In win-8 64 bit I have 2 folders. Program Files and Program Files (x86) , I am not sure whether to use ~ or " " to set JAVA_HOME and for 32 bit java or 64 bit java installed.
May be only java 1.6 is supported right now.
I searched and found similar issues :
I find this link but not able to get why its advised to set the system environment Path Variable to 'c:\windows\system32'.
In this link its advised to use InstallManager.jar via cmd.exe.
I can try each possible assumption till it works but hoping to find a solution with proper reason why I am getting this error.
If any one knows how should I work this out please help.
At last solve the Issue.
Installed jdk1.7.0_51 (I think currently JAVA 8 is not supported).
Set the JAVA_HOME as C:\PROGRA~1\Java\jdk1.7.0_51 (thanks to #Michael comment).
This link: https://answers.madewithmarmalade.com/questions/16878/cant-install-tizen-sdk-on-windows-8-64-bit.html solved for me the problem of Tizen SDK installation:
Change directory to %LOCALAPPDATA%\Temp\tizensdk_TimeStampOfInstallationInvocation
java -jar InstallManager.jar
My system: Windows 7 Ultimate x64. Java's version installed (64 bit):
g:>echo %JAVA_HOME%
c:\Program Files\Java\jdk1.8.0_05
g:>echo %CLASSPATH%
c:\Program Files\Java\jdk1.8.0_05\jre\lib
Added to PATH: c:\Program Files\Java\jdk1.8.0_05\bin\
(Tizen IDE and "Hello World" example run just fine.)
I encountered the same problem and finally I realised that my version of Tizen installer is 64bit but I installed 32bit java in my computer. Then I downloaded 32bit Tizen installer and everything was fine.
I encountered the same problem, and it was solved by placing the Java path in the beginning of the system path ! weird.. but worked :)
You must include, depending on whether you downloaded the x86 or x64 Tizen installer, C:\Program Files (x86)\Java\jre7\bin or C:\Program Files\Java\jre7\bin in the PATH environment system variable. You can't use java 8. See this oracle page for instructions on setting environment variables. I have read some others mention that they put the entry at the very beginning of the PATH variable. I think this would only matter if you also had an entry for java 8, but better safe than sorry.

My JDK home path in Android Studio is C:\Program Files\Java\jdk1.7.0_79.
I have JAVA_HOME variable: C:\Program Files\Java\jre1.8.0_111.I tried to change JAVA_HOME variable to C:\Program Files\Java\jdk1.7.0_79,but Android Studio did not start.
What should I do?
I ran into the exact same message with Android Studio 2.3.2.
I had installed Java SDK 7, and then accepted an update to Java 8.
After much ado following advises about setting environment variables JAVA_HOME, JDK_HOME, STUDIO_JDK and PATH in dozens of different combinations, I finally found out what at least my problem was and it's very simple indeed.
Turns out, the update to Java 8 was only for the JRE so the SDK was still 7, and Studio 2.3.2 requires JDK 8. So after installing that, not one single environment variable was necessary to get rid of the "This IDE is running on a Java JRE instead of" message.
Hope this helps.

I need to install spark 1.0.0 on my laptop, which has 64 bit OS windows 8, , java(java version "1.7.0_25"). I downloaded "spark-1.0.0-bin-hadoop2". But i don't know how to install spark 1.0.0. I also searched in Google but i can't find it properly. So can you please tell me the installation steps on windows 8 OS and what any other things are needed for this process ?
You just extract the file you downloaded and you're good to go. You can now run bin/spark-shell to start experimenting.
If your cluster environment runs Linux though, I would recommend using Linux for experimentation/development as well. Having a matching environment will avoid a number of issues.
Install Java 7 or later. Set JAVA_HOME and PATH variable as environment variables.
C:\java-version
Download Scala 2.11 or Scala 2.12 and install. Set SCALA_HOME and add %SCALA_HOME%\bin in PATH variable in environment variables.
To test whether Scala is installed or not, run following command in command prompt.
C:\scala -version
Download and extract it to any drive i.e. c:\program files\spark-1.2.1-bin-hadoop2.3.
Set SPARK_HOME and add %SPARK_HOME%\bin in PATH in environment variables
Run following command on command prompt.
C:\program files\spark-1.2.1-bin-hadoop2.3.\bin\spark-shell
Thats it. this is for windows OS.
Is there a way to prevent that the Java installation routine (e.g. jdk-7u1-windows-i586.exe) copies java.exe into C:\Windows\system32 directory?
I have to install my software on a client's laptop and I don't want to break other Java applications which are already installed on the machine. In other words I want to install a private JRE which is only used by my software.
By now, I copied an already installed JRE from my computer to the client's machine.
I discovered yesterday that there is a problem with Java versions on Windows, as you know keeping java up to date these days is critical, especially the JRE used by Internet explorer located in the Windows system32 or syswow64 folder.
You can perform a search for java in your C: drive and look at the various executable files it finds to determine if the situation applies on a specific system.
After doing some research I find that when the Java updater runs, it only updates the files installed in the JAVA home , usually located on the program files, but it does NOT update the files located in the windows system folder. As a result and since the system folder is in the default system PATH , the usage of Internet Explorer continues to use an old version of the JAVA files ( java.exe , javaw.exe , javaws.exe )
The solution is to uninstall java using the control panel uninstall programs feature, download most recent version and install again.
Cheers!

I recently upgraded to java 8 and discovered this problem as the java version under system32 was still java 7. It stops you even running version as it complains about the registry keys
U:\>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.
Doing the following pointed me to the culprit:
U:\>where java
C:\Windows\System32\java.exe
C:\Program Files\Java\jdk1.8.0_45\bin\java.exe
I 'solved' this problem by just deleting the java under system32! I'm unsure of what consequences this will have.
You can just provide the JRE you want to use on your software and:
Set the JAVA_HOME variable before you run your application
Point to the correct java.exe file (e.g. ..\jre1.5.0_22\bin\java <your_java_main>)
This can be done in a *.bat file for example.
After running the *.bat file you created, all other java version will be ignored and it won't matter which versions are, or will be, installed on that pc.
I found the newest JDK still doesn't write correct code against registry.
The issue is if a computer doesn't have JRE, JDK doesn't register JRE in registry correctly.
For those install JDK 1.7u72 Just add Software\JavaSoft\Java Runtime Environment as the error message indicate. And add a string entry of CurrentVersion with value 1.7.
And then add Software\JavaSoft\Java Runtime Environment\1.7 and put a JavaHome string entry with value "C:\Program Files\Java\jre7". And JRE will function correctly.
Blame Oracle, if you use Registry, then write correct code, otherwise don't use the Registry!
All you have to do is go to Control Panel -> Programs Uninstall a program. Uninstall the old java updates and keep the newest java update and java development kit update. Your newest java update and java development kit update should have the same number.
Windows 10 Solution
Check Java Version in Console (CMD) with java -version
Check in Console (CMD) with where java, which Java Path's are enlisted.
If it you shows you "C:\Windows\System32" in its output, you will have a problem to get to your %JAVA_HOME%, where your wanted Java version resides.
Meaning, you need to get rid of "java.exe" in "C:\Windows\System32".
Just uninstall the JRE in the Software ("Programs and Features")
Hint: Keep in mind, do NOT the JDK, here in my case "Java SE Development Kit 8 Update (64-bit)"), but the JRE.
One way I would try would be to create a write-only empty file with the name java.exe into the System32 folder.
I've been trying to use QT Jambi, but I couldn't manage to install it yet. First of all, this is my system:
Windows 7 Home Premium 64 Bit
Java 6 32 bit (I often use JDownloader which is not compatible with the 64 bit version of Java)
MinGW C++ compiler that comes with Code::Blocks (which sets all required environmental variables during setup)
I also have CygWin installed, but I don't understand why it gets mentioned during the error that I get...
My first idea was to try the 32 bit version since I have 32-bit Java, so I linked the libraries in Eclipse, tried the classical beginner program found in a tutorial and I got this message:

Exception in thread "main"
Then since it says it expects a 64 bit system I followed the Installation Guide and tried this steps:
1) Downloaded QTJambi source package
2) Downloaded original QT source package
3) Added "C:\QTJambi\QT\qt-qt\bin" (QT source package folder) to the environment PATH variable
4) Opened Visual Studio 2005 Command Prompt
5) cd C:\QTJambi\QT\qt-qt
6) Tried: configure -platform win64-g++ -D QT_JAMBI_BUILD -no-qt3support -plugin-manifests
But it didn't work, error: invalid option win64-g++ for -platform
7) Tried configure -platform win32-g++ -D QT_JAMBI_BUILD -no-qt3support -plugin-manifests
8) Digit o for open source
9) Digit y for accepting license
But it doesn't work either, getting this error:
Running syncqt...
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:

are supported and installed on your system.

Anyone able to help?
Thanks in advance to anyone!
This response attempts to explain and address the original problem (i.e. how to make use of the 32bit QtJambi binary distribution on a 64bit Windows system).
skipping because of wrong system: trying to load: 'win32', expected: 'win64'
This is a message from the QtJambi initialization code that detects a mismatch between the 32/64 bit-ness of the JVM and the 32/64 bit-ness of the QtJambi implementation trying to be loaded into the JVM instance at runtime.
In your case this is due to trying to use a 64bit JVM with a 32bit version of QtJambi. This is not a possible feat. To correct the problem find and install directly the Windows 32bit JVM on your system so that you have the file "C:\Program Files (x86)\Java\jre6\bin\java.exe" (you may already have it installed, please check)
When they are both installed on a 64bit system take a look at the difference between:
C:\>"C:\Program Files (x86)\Java\jre6\bin\java.exe" -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)
C:\>"C:\Program Files\Java\jre6\bin\java.exe" -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)
The top one is the 32bit JVM; the bottom one is the 64bit JVM.
Now try loading the QtJambi binary version you have via the 32bit JVM you have to do this explicitly as the default "java.exe" should be the 64bit one on a Windows 64bit platform:
"C:\Program Files (x86)\Java\jre6\bin\java.exe" -cp qtjambi-X.Y.Z.jar;qtjambi-win32-msvc2008-X.Y.Z.jar;myjar.jar mypackage.MyMain
You need to fixup the command line above the ClassPath (-cp) to the locations of your JARs you are attempting to run and the main().
If you have problems getting the application to start due to UnsatisfiedLinkError and you are using a msvc2008 build then try installing the "Microsoft Visual C++ 2008 SP1 Redistributable Package (x86)" http://www.microsoft.com/download/en/details.aspx?id=5582 (NOTE: There is also a 64bit version of this as well, this link is for the 32bit version which is relevant to using 32bit QtJambi on a 32bit JVM, if you also want the 64bit version search for the same page with "(x64)" in the title instead of "(x86)" on the microsoft website).
Then retry your test.
Qt Jambi nowadays supports 64 bit compilations too, but getting proper Qt is quite a bit harder.
For MinGW there is some resources available in Internet. Maybe they can help you. Building 64-bit Qt 4.7 using MinGW-w64
Only supported (by Nokia) solution at the moment is 64 bit MSVC compilations, but AFAIK there is no such binaries distributed from Nokia because runtimes are not allowed to be freely distributed. When compiling with MSVC, correct profile for MSVC 2010 would be win32-msvc2010. List of those can be found from in mkspecs directory.
Note that you don’t usually have to specify the profile in first place; only if there is many available profiles you could use and you want to use certain one (MinGW or MSVC, for example).
64 bit compilation with MSVC works using 64 bit environment, according this page.
Using Cygwin with Qt or Qt Jambi is not really suggested; use MSYS if you want unix-like environment.
I'm having a problem getting my android dev environment setup in Windows 7. I follow the instructions here, as well as several environment sublinks. I am using Eclipse with the Android plugin. I have installed the Java JDK several times, in various locations (jdk-6u20-windows-i586.exe) - but I am obviously missing something.
Every time I run "android create avd --target 2 --name my_avd" I get an error:
C:\Users\andrew>android create avd --target 2 --name my_avd
WARNING: Java not found in your path.
Checking it it's installed in C:\Program Files\Java instead.
ERROR: No suitable Java found. In order to properly use the Android Developer
Tools, you need a suitable version of Java installed on your system. We
recommend that you install the JDK version of JavaSE, available here:
http://java.sun.com/javase/downloads/
You can find the complete Android SDK requirements here:
http://developer.android.com/sdk/requirements.html
This error message is the reason for me installing the JDK several times over. First I tried installing to a location on my e: drive. I then moved it to the default loc (program files (x86)\java\jdk.6.something. I also tried forcing it to go into the program files\ path, but it still automatically installs into the (x86) path. I have added the install path to my path environment variable every single time, yet I still continue to get this error. My suspicion is that windows 7 and the android tools are not playing together well in terms of finding the JDK, but who knows, it may be something entirely different. If you have seen this error before, I would appreciate a hint.
I had this same problem, after accidentally installed the 32-bit version of Java SDK. I uninstalled it and installed the 64-bit version (since I'm using Windows 7 64). The Android SDK setup never found Java correctly, even after I added it to my PATH variable!
After a bit of digging around, I discovered a java.exe floating around in my system32 folder, which in the order of the PATH variable came before my SDK path. After whacking the java.exe in my system32 folder, the Android Setup ran just fine!
Hope this helps.
The android command is just a Windows Batch file which in turn uses the batch file tools\lib\find_java.bat to find Java.
Having a look at the source, it does the following:
Looks to see if java.exe is on your PATH.
Looks for java.exe in somewhere under %ProgramFiles%
Your problem arises because you're using the a 64-bit version of Windows. This means %ProgramFiles% is C:\Program Files but Java is installed in C:\Program Files (x86) as it's a 32-bit application, meaning find_java.bat doesn't find it.
So to fix this you'll need to add the directory containing java.exe to your PATH environment variable.
You'll need to the add the directory containing java.exe - something like C:\Program Files (x86)\Java\jdk6\bin - on to the end of PATH with a semicolon in front of it to separate it from the previous entry.
This question on superuser.com covers maintaining Environment Variables in Windows 7.
It is really hell with JDK detection...
My params: Win 7 x64 + JDK x64 (JDK path (c:\Program Files\Java\jre7\bin)
Was googling and playing around with env variables may be 1 hour - no way.
Finally come with such solution
Manually edit android-sdk-windows\tools\lib\find_java.bat by hardcoding the path to java.exe
set java_exe=c:\Progra~1\Java\jre7\bin\java.exe
if not defined java_exe goto :CheckFailed
:SearchJavaW
set javaw_exe=c:\Progra~1\Java\jre7\bin\javaw.exe
if not exist %javaw_exe% set javaw_exe=%java_exe%
goto :EOF
Thats works for me.
In the SDK tools folder go to libs and edit find_java.bat. It can usually be found in C:\Program Files (x86)\Android\android-sdk-windows\tools\lib.
Change all instances of %PROGRAMFILES% to %PROGRAMFILES(X86)%.
I did this and the error went away.
Find android-sdk-windows\tools\lib\find_java.bat and add something like the following:
set java_exe=
call :TestJavaDir "%JAVA_HOME%"
if defined java_exe goto :EOF
What worked for me was this:
add a path to your java/bin directory to the system Path variable. Do NOT include java.exe.
Steps on Win 7 64bit:
Click Windows Button
Right Click on Computer
Select Properties from the Context Menu
Click Advanced System Settings on the top left section
Click the Environment Variables... button at the bottom of the properties dialog
On the bottom list (System variables) find the "Path" variable
Click the Edit button
Go to the end of the textbox and type something like c:\program
files\java\jdk1.6.0_26\bin (make sure it matches the name of your
java directory!)
Click OK
Click OK
Click OK
Try it out!
hth,
\ ^ / i l l
I put rem statement in android.bat after the call command and hardcode the path of \bin\java.exe:
rem Check we have a valid Java.exe in the path.
set java_exe=<..>\jdk1.6.0_31\bin\java.exe
rem call lib\find_java.bat
if not defined java_exe goto :EOF
Same for setting other variable javaw_exe thus:
set javaw_exe=<..>\jre1.6.0_31\bin\javaw.exe
if not exist %javaw_exe% set javaw_exe=%java_exe%
goto :EOF

I also had this same problem
-> accidentally installed the 32-bit version of Java SDK -> uninstalled -> installed the 64-bit version (Windows 7 64) -> -> the Android SDK setup never found Java correctly!
I discovered a java.exe floating around in C:\Windows\SysWOW64 folder.
After renaming this java.exe to javaX.exe, the Android Setup ran just fine!
