Silent install isn't completely silent - it triggers a browser to open up Couchbase Console

Also raised here: CBD-1832, please feel free to close one as duplicate as needed.

Summary: The Couchbase installer, even when running unattended (per docs: http://developer.couchbase.com/documentation/server/4.5/install/windows-install-unattended.html) will still pop a URL to the couchbase console (e.g. http://localhost:8091). This could cause issues where this behavior is not expected. Specifically when trying to create a Chocolately NuGet package: https://chocolatey.org/packages/couchbase-community/4.0.0

Repro is to run according to docs (link above).

Expected: No website popup (or maybe a separate flag to silence the website popup)

Actual: Website pops up no matter what.

This issue seems specific to Windows and is an issue when using https://chocolatey.org/.

From what I can tell, the popup is triggered from here https://github.com/couchbase/voltron/blob/master/win/server/Script%20Files/Setup.Rul#L1324:

if (MODE !=SILENTMODE && !PortTaken(szPort)) then

    MessageBox("Looks like Couchbase Server doesn't respond in time.\n" +

               "Please manually refresh browser and wait for the Admin Console to fully start.",

               WARNING);

endif;

LaunchBrowser(szSite);

This is in the 'OnFirstUIAfter' function, which is triggered after the file transfer has completed (this is part of the InstallShield framework I think).
I think that the LaunchBrowser command should be within the if statement checking if it is in silent mode so that it doesn't pop up if in silent mode.
