Thanks again. Now I understand.

I like your solution of including a separate JRE, which eliminates compatibility issues with Sweet Home 3D when the registered JRE is updated.

Thanks for the quick and detailed answers. I will give Sweet Home 3D a try.

I have other applications that depend on Java, such as LibreOffice. If I uninstall Java before installing Sweet Home 3D, will other applications use the Java that comes with Sweet Home 3D?

Or are the two instances of Java ...

I am interested in installing Sweet Home 3D on my Win7 x32 PC, which has the latest Java installed. I disable the Java plugins in Firefox and block internet access by Java with a firewall because of Java security vulnerabilities. See http://krebsonsecurity.com/2012/03/new-java-attack-rolled-into ...
