Upgraded to Nik Collection 4 on Win 10 64bit. When attempting to access Silver Efex 3 or Viveza 3 as filters from Photoshop CC I get the following message disk full message:
None of the drives are anywhere near full. All the other filters work from Photoshop. Silver Efex and Viveza both work as stand-alone programs and from Photo Lab 4.
I have seen a suggestion that the issue may be that the path is incorrectly set during installation, but can’t see where to change it. I did notice that both program’s config files only contain options for us and jp as regions.
