I changed my fortls path to ```auto "fortran.fortls.path": "C:/Users/dwbroad/Anaconda3/Scripts/fortls.exe" ``` And this made the error message disappear. ---

You could try to add `C:/Users/dwbroad/Anaconda3/Scripts/` to your PATH environment variable. IIRC Anaconda won’t do this by default but instead expect you to run their activation scripts when opening a terminal. Personally I prefer regular Python because I’ve had so many problems like this with anaconda ---

Thanks, I added it just to be safe. But I found out that just changing my fortls path did the trick ```auto "fortran.fortls.path": "C:/Users/dwbroad/Anaconda3/Scripts/fortls.exe" ```
