You can just provide the JRE you want to use on your software and:

<ul>
<li>Set the <code>JAVA_HOME</code> variable before you run your application</li>
<li>Point to the correct java.exe file (e.g. <code>..\jre1.5.0_22\bin\java &lt;your_java_main&gt;</code>)</li>
</ul>

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 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!

blocks|key|3138446|text|我发现最新的JDK仍然不能针对注册表编写正确的代码。问题是如果计算机没有JRE，JDK就不会在注册表中正确注册JRE。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3138447|对于那些安装JDK1.7u72的用户，只需添加Software\JavaSoft\Java+Runtime+Environment，如错误消息所示。并添加值为1.7的字符串项CurrentVersion。然后添加Software\JavaSoft\Java+Runtime+Environment\1.7，并放置一个值为"C:\Program+Files\JavaJRE7“的JavaHome字符串条目。并且JRE将正常工作。责怪Oracle，如果你使用注册表，那就写正确的代码，否则就不要使用注册表！|3138448|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

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!

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

<pre><code>U:\&gt;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.
</code></pre>

Doing the following pointed me to the culprit:

<pre><code>U:\&gt;where java
C:\Windows\System32\java.exe
C:\Program Files\Java\jdk1.8.0_45\bin\java.exe
</code></pre>

I 'solved' this problem by just deleting the java under system32! I'm unsure of what consequences this will have.

By now, I copied an already installed JRE from my computer to the client's machine.
