Changing This Parameter

On the Advanced Memory page of the Management Portal (System Administration > Configuration > Additional Settings > Advanced Memory), in the PythonRuntimeLibrary row, select Edit. Enter the location of the Python runtime library you want to use.

Instead of using the Management Portal, you can change PythonRuntimeLibrary in the Config.configOpens in a new tab class (as described in the class reference) or by editing the CPF in a text editor (as described in Editing the Active CPF).

When you edit this setting, it takes effect immediately. The new runtime library is used for any new processes.
