The built-in HTTP Server is not listening on port xx

[juwagn]

Hello,

firstly run cmd.exe with admin rigths and execute
netstat -anb
if you see something is listening already on ports 80 or 443 but it is not HTML5service.exe then possibly some Microsoft service is listening.
If it was IIS, then disable IIS on ports 80/443, if that did not help and still some system service is taking port 80 continue with following FAQ.
------------
By using IIS as third server sometimes it is not possible to force IIS to stop using port 80, mostly caused by running Microsoft SQL server.
To move Microsoft SQL from port 80 as example to port 81 do following.

1. Open - Start > Programs > SQL Server 2008 R2 > Configuration Tools > Reporting Services Configuration Manager
Sometimes it is not exactly named so as described above but should be called similar
2. Open - Web Service URL
3. Change port as example to 81
4. Open - Report Manager URL > Advanced
5. Click on entry with port 80 > Edit
6. Change the port to same as in step 3.
-------------

If ports are not bound and Tsplus still does not start then check if Java/Java64 bit is installed.
Check that path to Java in **TSplus installation folder**\Clients\webserver\runwebserver.bat
refers to right folder as example @"C:\Program Files\Java\jre1.8.0_111\bin\HTML5service.exe" **********the rest*************
if on 64bit system you see C:\Program Files (x86)\ in Java path then you don't have Java64bit, install it from
https://java.com/en/download/manual.jsp > Windows Offline (64-bit)
