Same here.

Sweet Home 3D v. 4.3 on Mac OS X 10.9.

If you double click the icon it just does nothing.

In a terminal If I run:

$ /Applications/Sweet\ Home\ 3D.app/Contents/MacOS/SweetHome3D
[JavaAppLauncher] Requested [1.5*], launching in [1.7] instead.
JavaVM: Failed to load JVM: /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bundle/Libraries/libserver.dylib
JavaVM: Failed to load JVM: /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bundle/Libraries/libserver.dylib
JavaVM FATAL: Failed to load the jvm library.
[JavaAppLauncher Error] JNI_CreateJavaVM() failed, error: -1
$

I have a file created with version 4.2 on Mac OS 10.8 called Home-2ndFloor.sh3d

In a terminal if I run:

$ open Home-2ndFloor.sh3d
LSOpenURLsWithRole() failed with error -10810 for the file Home-2ndFloor.sh3d

I installed the version that is bundled with Java.

Any idea what may be wrong? How to fix it?

Thanks,
