We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

I resolved it myself after trying different configs…and this is the one that worked for me: 
”\\xxxx-shares\SiteSoftware\xxxx\Engineering\Ansys STK\Ansys_STK_Pro_v12.7.1\STK_v12.7.1\install.exe” /s /licenseagree /licserverinfo 1055:xxxx-LIC-SRV

If you are testing your silent install script, you may want to re-image your machine before implementing a new script as the licserverinfo is stored.  

Hope this helps someone in the future.
