After installing the Modeler extensions for Analytic Server onto Modeler Client or Server version 188.8.131.52 or 184.108.40.206 the new nodes are not available within the program. The installation completed without error.
Unable to access Analytic Server nodes
The extensions installer will work with any version 15 installation, but the nodes will only appear if Modeler's Fix Pack 2 has been installed.
Diagnosing the problem
Check the Modeler Fix Pack level (Help->About->Additional Details).
Resolving the problem
Installing Modeler Fix Pack 2 should cause the nodes to appear on the next launch (no need to reinstall the extension).
