====== Errors and Solutions ======

{{:captcha_breaker:cb_webserver_error.jpg?nolink|}}

It can happen that you get an error like the above when you startup the program or try to enable the web server. This happens often on a [[search_engine_ranker:introduction#application_hosting|VPS]] where W3SVC is installed and enabled by default. This means that the required port 80 is already used.

There are now two solutions to this problem.

** You simply disable the web server option.**

This might sound too simple but the web server is only required if you use the program with tools other than [[:search_engine_ranker|GSA Search Engine Ranker]]. If you still have problems getting it to work, try starting [[:search_engine_ranker|GSA Search Engine Ranker]] as admin (right click on icon -> Run as Admin).

**You have to find out what program is listening on that port.**

This can be very complicated and hard to figure out. The error message shows you some typical programs that might block the program from working as a web server. If you find them, stop or "kill" them with the task manager. You can also try to use netstat. You can do that when typing this **netstat -b** in the console (press start -> Run -> cmd [Enter]).

You can use [[http://www.nirsoft.net/utils/cports.html|CurrPorts]], a windows program by NirSoft that will list all used ports and the program using it. It should be very easy to see what is running on the IP/Port using this tool.

If you see that error from the screenshot but with //xxx.xxx.xxx.xxx://**81??** (port 8123 - 8131), then simply disable the simulation of DeathByCaptcha as this is the SocksAPI being simulated on a different port range.
====== How to disable IIS - Microsoft Web Deploy ======

It's usually IIS (Microsoft __I__nternet __I__nformation __S__ervices) that is sitting on port 80 and avoiding a proper use of Captcha Breaker.
You have to disable it by clicking:

Start Menu -> Control Panel -> Administrative Tools -> Services 

There you can disable it when changing Automatic startup to disabled.
search for **Microsoft Web Deploy** or **MsDepSvc.exe** or **MsDepSvc**.

Or simply open the TaskManager and find the service as seen in the screenshot below. The right click on it and choose **Stop Service**

Another way to stop using ISS to use port 80 is:
  - start RegEdit (typed regedit by using Win + R)
  - go to the key **HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP**
  - changed value of the "**start**" value from **3** to **4**
  - restart PC or VPS

====== How to disable World Wide Web publishing service ======

Another common service that uses port 80 can be disabled as follow:

  -     Click Start button, type services in the Search box, and then click Services under Programs.
  -     Locate and then double-click World Wide Web Publishing Service in the list of services.
  -     On the General tab, click Stop under Service status.
  -     In the Startup type list, click Disabled, and then click OK.
