Illegal character error with Run command

[KilliK]

Hello.
I am using the below command in CMD with all its parameters with no problems. the double quotes are necessary for the app to work correctly.
"C:\Program Files (x86)\Youtube-dl\youtube-dl.exe" -f "best[height=720]" -o "C:/Storage/%(title)s.%(ext)s" URL

To run the same command from inside an AHK script, I only added the Run command:
Run, "C:\Program Files (x86)\Youtube-dl\youtube-dl.exe" -f "best[height=720]" -o "C:/Storage/%(title)s.%(ext)s" URL

The problem is that when I try to run the script I am getting an error:

The following variable name contains an illegal character:
"(title)s."

The program will exit.

The conflict must be with the special symbols in that specific parameter. I tried triple quotes and double percentages and an accent before the dot but the problem remains.
Any idea how to fix this?

Try a backtick before the % for a literal %: `%
Otherwise it sees the start of a variable e.g. %var%

I did that but i am getting the same error.

Expression syntax > traditional syntax

Code: Select all

Run,% """C:\Program Files (x86)\Youtube-dl\youtube-dl.exe"" -f ""best[height=720]"" -o ""C:/Storage/%(title)s.%(ext)s"" URL"

If that also doesn't work, try running it through comspec.
