For issues related to Lightroom Classic CC and Negative Lab Pro

Version 2.3 missing “destination folder”: I followed the instructions for updating my version 2.2 to 2.3 in Lightroom Classic on my Windows 10 computer. In Develop module, I opened Negative Lab Pro and, using Source Digital Camera, Color Model Basic and Default saturation, clicked Convert. I got an error message: he destination folder for this operation is missing. C:Plugins\NegativeLabPro.lrplugin\previews. True enough, there is no folder “previews” in my NLP.lrglugin folder. What am I missing?
