If 80 port is used by other program/service, X-Spinner will not work, you need close the program/service that is using the 80 port. Then try to Start X-Spinner again.
So the first step is to find which program/service are using the 80 port, usually you should stop following service in windows first >>
World Wide Web Publishing Service
Web Deployment Agent Service
SQL Server Reporting Services (MSSQLSERVER)
You can go Start > Control Panel > Administrative Tools > Services, and then stop these service.
Then try to star X-Spinner again, if it still can't work, check more help at >>
