By the "paid version", do you mean the Microsoft Store version?
While the Store versions comes with winscp.com, it is not easily available due to limitations of the platform: UWP console app with no icon, just execution alias.

You can use an absolute path, but it changes with every update:

You better download the portable package and use that.

I downloaded WinSCP – the paid version. I cannot seem to locate the .com executable and cannot run from the command line. I am looking to automate folder creation on a local machine and push to a Synology NAS.
