Unable to open VPM due to error "VPM Editor cannot be launched from this file"
When launching the VPM editor in Management Center, the following error message is seen:
The Java Network Launch Protocol (JNPL) file is old and needs to be update in order to open the VPM.
Using Management Center to manage ProxySG policies.
Open the VPM Editor with the new JNPL file when the VPM launcher window opens in the browser.
This might still fail in some versions of java but there are 2 known workarounds at this time.
