I cannot start new JIRA Servicedesk (Windows version) on same port, as previous JIRA SD installation, even old JIRA and service was uninstalled and deleted. JIRASD service is started but no answer on desired port. After changing port to some new TCP port new instance work fine. Previous TCP port isnt used, checked twice with netstat -an. Any idea where can be any leftovers (registry, java dir, etc.)?
