I followed all the correct steps and I'm still getting a "Invalid argument" error. Here the steps:
Manually install ed from here: https://gnuwin32.sourceforge.net/packages/ed.htm. Setup file is the ones that says "Complete package, except sources".
Adding the path (C:\Program Files (x86)\GnuWin32\bin) to the PATH system variable (tried with local variables too).
Tried running this command from Command Prompt and Powershell with elevated privileges:
"C:\Program Files (x86)\GnuWin32\bin\ed.exe" "{full-path-to-some-file.txt}"
I invariably get an "Invalid argument" error.
If I try to run just "ed", I get the same.
But if I type "ed --version" I get:

And I type "ed --help" I get:

So it seems to me that is correctly installed, but I still can't use it? I'm so confused.
