To run the Wolfram Engine on your Windows machine, you need to get a free license, install the program, then activate the product.

You need a Wolfram ID to activate the Wolfram Engine. If you do not have one already, you must create one.

If you are connecting to the internet via a proxy server, WolframScript needs suitable proxy information in order to be able to activate the Wolfram Engine. WolframScript uses the operating system’s proxy settings, which can be set by executing (from the Windows Command Prompt):

netsh winhttp set proxy (proxyserver):(portnumber)

For example:

netsh winhttp set proxy
