Not opening RW2 file

I installed 5.01 raw therapee on windows for Panasonic’s G7 cameras… makes RW2 using 16 bit… not seeing photos ??? will only show Jpegs. I open up the folder and when I click on the image number… nothing shows up in the window of the program. Oddly enough when I used the Jpeg and RW2 combined option on my camera, it allow the RW2 to be seen???

All I see are dots and question marks, some version “5.01” which does not exist and a textual representation of abstract art. Re-read what you wrote to make sure it’s intelligible before posting.
