How to install the haldCLUTH folder in Rawtherapy. Thanks
On Linux I used /home/.config/RawTherapee, on Windows
…\AppData\Local\RawTherapee where I created a subdirectory. I think the path could be anywhere.
But you have to enter the path in “Settings”!
Done but I can’t access AppData Local settings
In windows explorer go to View / Options
go to tab view and look for “Hidden files and directories”, there is an option “show hidden files, directories and drives” which you should check.
save and close
(I have a german installation, so some words can be wrong)
Start RT, open “Preferences”
goto tab “Image Processing”
under “Directories” click on “HaldCLUT Directory”
right click in the shown dialog
check “Show hidden files”
Navigate to “C:\user\username\AppData\Local\Rawtherapee”
If this doesn’t work, it should be possible to create the directory in …\documents
Kurt thanks for everything, I solved it, the problem was that I didn’t see the open button because it was hidden under the bar.
Anything that can go wrong will go wrong… 
True
You might also copy the HaldCut files into a subfolder of your RT installation
