"Cannot start command: ... " error

"Cannot start command: Downloading Engine 96.0: assign: The parameter is incorrect"

As user on steam was reporting this one, he got this error in both springlobby and weblobby standalone. It happens when he joins or starts a battle.

I have never heard of this one and the forum search is finding nothing.

this error message is specific to weblobby. springlobby has pr-downloader "integrated" it doesn't need to start an external process to download stuff.
