Backward Incompatibility Viveza

Viveza 3 is not compatible with Viveza 2 adjustments applied to smart objects in Photoshop. The Viveza 2 smart object layer is inactive and does not launch anything. This incompatibility has been confirmed during a support ticket inquiry. NIK has not said whether this is a bug to be fixed or part of the new design (that is, intentional, with no intent to fix).

If true, it’s a BIG MISTAKE of DxO to kill an existing Vivzea 2 installation by default,
while not to mention the incompatibility. – The only ‘indication’ is this chart
