In my case, I tried version 5.2, using the windows installer, but with no success. The only thing that worked was as I described in my previous post.

I had the same problem. Windows 10. Java 8.

I solve the problem doing this:
-Install Java 7.
-Download Sweet Home 3D in the JAR version.
-Create a .BAT file that calls the JAR, something like this: "C:\Program Files\Java\jdk1.7.0_79\bin\java.exe" -jar sweet-home-3d.jar
