Hi Rhona, I have loved Sweethome for years and it's simply awesome! However this Windows 10 issue is going to be a killer to most 'non-tech users'.

Emmanuuel gave a FAQ link (see above), installing Java JRE. Then @Nightmare says it was solved with Java VM. It's quite confusing however and it's not easy to install I think.

Someone really needs to post a clear "Step-By-Step" to install the Java 32 into Windows 10 until there's a fix.

This SH3D has such potential, but this W10 issue could slow it's use dramatically.
