You mixed Java and Java 3D versions. Sweet Home 3D is delivered with Java 1.8.0_181 and Java 3D 1.6.1 / 1.5.2.

I have to ask, if the application is that picky about the version it wants, why do you not know which version that is?

It's not the application which is picky, it's the graphics drivers! I just try to provide a solution that works on as much as possible computers, but you reached the limit.
