Multiple ManageEngine software on the same server

Multiple ManageEngine software on the same server

Hi guys. A little help. I installed ServiceDesk Plus on my server and it's working, now I want the integration with ADManager, ADSelfService and OpManager but I need to install on the same server ServiceDesk was installed. When I start ADSelfService it throws an error saying pg_ctl.exe doesn't exist or is in use. ADManager works well and OpManager either. Can I install ServiceDesk and ADSelfService on the same service? How? Thanks for the help.
                New to ADManager Plus?

                  New to ADSelfService Plus?
