License not being set

I’ve read through documentation, ive read through forums and cant seem to figure out the issue.

First, i went and downloaded the license from my account. Next i downloaded dll package for a version that was released before the expirey of my license.

I have both the dll and the lic files in the same folder and have also set the liense in code using the file name as directed.

Then i try to execute code and get the at most 4 elements(for any collection) error for evaluation mode.

Is there something i am missing? Thank you!
