It is possible that the Bonjour service failed to start during installation. Windows Installer service should have offered to restart the machine in such case. Restarting Windows manually or starting the Xamarin Bonjour Service manually from the Control Panel should work as a fix.

Looking at the screencast, we have a number of opportunities to tell the user the right actions to take here.

Either the diagnostic tool step or the bonjour error should tell the user to restart the service and/or restart their computer.

Putting this on the Big Splash in case we can fix this with just a text update on the error message.

If not, please put to V2
Comment 4 Dominique Louis 2013-01-22 12:50:43 UTC
Pj Unfortunately the diagnostics does additional steps to determine networks issues.

I think it would provide a better UX, but in V2 where we can maybe use the diagnositics classes to determine if everything is ok first before instantiating ZeroConfDiscovery().

Jose any suggestions?

I'll move to Splash 2.

We need to know if Xamarin Bonjour Service is installed in the target machine.
Comment 6 Marek Habersack 2013-05-08 08:20:39 UTC
Jose, it won't be if Apple Bonjour exists

Is there a fix for this problem available?
I've tried to manually delete the registry keys which were related to the Bonjour Service and which haven't been deleted after uninstalling all Xamarin software.
This broke my Windows system and I had to use Windows Restore to go back to a working system snapshot. Now that I know that iTunes or other Apple Software is using Bonjour, I might have the reason why my system broke.
Comment 9 Dominique Louis 2013-05-28 05:57:09 UTC
We believe these issues are caused by the fact that there is a Apple/Xamarin Bonjour Service on the machine, but it may not be working correctly. For those with either not working, a repair may be in order.

So to that end the change I've just push for the iOS installer will check to see if Apple Bonjour is already installed. 
If it is installed and not running, before the installation finishes, it will attempt to start the service. 
If the service starts within 60 seconds, then we know Bonjour is running.
If the service failes in some way, a registry entry will be created in 
HKEY_LOCAL_MACHINE\SOFTWARE\Xamarin\iOS\IsBonjourInstalled That will list the state of the Bonjour and a message, hopefully explaining the issue.
In this scenario, the user will need to fix their Bonjour installation before using the iOS product on Windows.

If no Bonjour service is found, just as it does now, it should install a Xamarin Bonjour service, and start it before the installation completes.

The only other changes is that to avoid clashes with subsequent Bonjour installers, when Xamarin.iOS is uninstalled. It will leave the Bonjour Service behind, as we risk breaking things due to the fact that our and Apples use the same name. Using different names would cuase a responder conflict.

Heyo Dominique, in your testing for the fix, were you ever able to reproduce this issue on command? (Aka, get into the "there is a Apple/Xamarin Bonjour Service on the machine, but it may not be working correctly" state?

I want to make sure we can properly verify the fix.

Today, we have checked this issue with latest builds:

MTVS 1.3.227
Windows 8 and 7
VS 2010/12
X.iOS  Server)

Now, On creating iOS application on VS, it does not give error pop up 'Bonjour initialization failure'. User is able connect to mac server successfully and able to run application on mac server successfully.
Comment 13 Kate Johnson 2016-04-27 12:58:50 UTC
All the above messages seem to suggest that this problem has been fixed and yet here I am with this same problem.

Service 'Bonjour Service' failed to start.

How can I fix this?
