Version 12 of CDFPlayer includes wolframscript but, contrary to previous versions of CDFPlayer installations, this time wolframscript does not work out of the box. Instead, it requires ID and passwd. I tried to insert my Wolfram user ID and passwd but it does not work. On the other hand, it tells you to get a developer license for free at Wolfram Engine for Developers License , but that page does not exist (yet?).
What is going on?
Thanks
The page Wolfram Engine for Developers License (redirecting to Wolfram Engine for Developers License) does exist now. Does that Free Wolfram Engine for Developers work for you?
