I'm using ArcGIS SERVER v11+Portal for ArcGIS + ArcGIS PRO 3.0.3 + Postgres 13.16 + postgis 3.2.
I licensed ArcGIS SERVER v11 using a *.prvc licensing file. Now, I need a Autorization file to create Enterprise geodatabase on Postgres SQL. How I can got the *.ecp file/authorization file? The paths indicated on the following image (popup of authorization file) doesn't exixt on my server. My ArcGIS Server and Portal for ArcGIS work fine and ArcGIS Pro is connected correctly to the portal too.
Opening *.prvc file I can read ECPXXXX code.

the ArcGIS Pro user's guide (https://pro.arcgis.com/en/pro-app/latest/help/data/geodatabases/manage-postgresql/setup-geodatabase-postgresql-windows.htm) says:
"You may need to copy the keycodes file from the ArcGIS Server machine to a location that the Create Enterprise Geodatabase geoprocessing tool can access." but there'isnt details regarding the steps to apply.
In the end I need st_geometry.dll file because into myesri under v.11 version I didn't find it.
Thank you
