I downloaded SE2017 Standard.
At the "Request a trial license" step it says:
A newer version of this product has been released. Please download and install our current product before requesting a trial license.
The download link in that message (
https://customer.slickedit.com/products) leads to a 404 error.
I called the number listed at the bottom of the SE home page (800-934-3348), but it seems to be disconnected/fast-busy.
I called the other number (919-473-0070), and it eventually takes me to voice mail.
I guess no one tries to install a trial version very often
