I am having the same problem...

I have Sweet Home 3D version 5.7 and Java jre1.8.0_171 installed on an Asus G752VL i7 2.6GHz processor with 12GB ram running Win10 64bit.

Replacing the Sweet Home 3D bin & lib files with the Java bin & lib files did not correct the issue.

Does anybody have any ideas?

Thanks in advance for your help...
