Error: Registry key 'Software\JavaSoft\Java Runtime Environment'\CurrentVersion'? [duplicate]

Answer 1

I had Java 1.8 but had to downgrade to Java 1.6 for some reason. When I uninstalled java 1.8 and ran the command "Java -Version" from the command prompt, I got the error -

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

has value '1.6', but '1.8' is required. Error: could not find java.dll Error: Could not find Java SE Runtime Environment.

Uninstalling 1.6 and then reinstalling 1.6 fixed the issue for me :-)

Answer 2

Other times you might have installed Java 7 and 8 both or twice, and from Add/remove programs unistall one of them and it should work.

Answer 3

On my Windows 7 machine, it was solved by doing the following:

1. In the START menu type "regedit" to open the Registry (be careful doing this)
2. Go to "HKEY_LOCAL_MACHINE" on the left-hand side registry explorer/tree menu
3. Click "SOFTWARE" within the "HKEY_LOCAL_MACHINE" registries
4. Click "JavaSoft" within the "SOFTWARE" registries
5. Click "Java Runtime Environment" within the "JavaSoft" list of registries
6. Highlight "CurrentVersion" (should see it in the main registry key explorer window on the right)
7. Change version to "1.7"

That is all... should work. Short of that, if you've already tried some other guides and/or messed up your registries, the most certain way to deal with the problem is to delete all previous versions of Java (using "Programs and Features" uninstall process) and then re-install just the version you want to work with. I'd suggest the distribution site at: http://java.com (as it usually has the most stable version)

Or look for a specific version you need from Oracle's site: http://www.oracle.com/technetwork/java/javase/downloads/

Answer 4

you may follow these steps :

• set JAVA_HOME to jdk[without bin folder]
• set PATH as %JAVA_HOME%/bin;
• put java.exe , javaw.exe & javaws.exe to C:\ProgramData\Oracle\Java\javapath [I was having problem here].
• double click on the java.exe
• Also check and edit the registry value for JAVA current version if required.

it worked for me :)

Answer 5

Your java version is 1.5 (you have jdk 1.5). The jar requires java version 1.7 (you should have jdk 1.7). You should download and install the 1.7 jdk from this website:
