Question

When I run:
C:\Users\ashahria\Downloads>java -jar schemaSpy_5.0.0.jar

I get the error below. What is wrong? How can I fix it?

Error: Registry key ‘Software\JavaSoft\Java Runtime Environment’\CurrentVersion’

has value ‘1.5’, but ‘1.7’ is required.
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.

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:
