After installing FORTRAN IntelliSense extension, then when using in a file by Select Language Mode keep getting a popup

enter image description here Error spawning fortls: Please check that fortran-language-server is installed and in your path.

So in Settings of VSC go to Extensions > Fortran IntelliSence

enter image description here

and have this word as path fortls assumed it would be a environment variable, but doesn't seems to be the case since it doesn't exist one by that name.

In the extension documentation is refered:

Configuration Note: When setting an explicit language server executable path on Windows backslashes must be escaped (ex. C:\path\to\fortls.exe).

but can't find anywhere this executable so what is the correct path for this extension/executable?

note: the extension is located at C:\Users\Username\.vscode\extensions\hansec.fortran-ls-0.6.2

OS: Windows

installed in the Visual Studion Extension enter image description here

In Ctrl+Caps Lock+P Preferences: Configure Languages Specific Settings

"fortran-ls.executablePath": "C:\Users\XXXXXX\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\Scripts"

or enter image description here

created environment variable called fortls that also haves its value that path and added to the PATH environment variable.

Make sure the Fortran language server is actually installed. (Usually installed via python pip. For example:

pip install fortran-language-server

For me, it was installed in c:\users\user\AppData\Roaming\Python\Python310\scripts\fortls.exe

You can verify via running with --version option.

After installing the Fortran Intellisense extension either set the executable path setting to the your install path (c:\bla\bla\fortls) OR, in the settings.json (don't forget to escape backslashes in the .json). For example:

"fortran-ls.executablePath": "C:\\Users\\user\\AppData\\Roaming\\Python\\Python310\\Scripts\\fortls",

If you cannot find the fortls.exe, just search for it using windows file explorer. Assuming you only have one drive, search c:\ and use the following search script:

file: fortls.exe

It may take a while, but it should show up in the search results.
