I see at least 4 ways my windows service could be installed.

 

My goal is to be able to call some custom code so that I can set the
username and password for the service by looking up and decrypting a value
from the registry. Therefore I do not think that <ServiceInstall> is an
option. The remaining ways I see to do this are the following and would like
any suggestions on what is best and can fully support install, uninstall,
rollback and commit. Thanks, Dave

 

1.       Run an imbedded installutil.dll like my original MSI file did and
is suggested here
http://avinashkt.blogspot.com/2007/05/how-to-create-installer-using-wix-whic
h.html - this seems complete but if possible I would like to not carry the
baggage of the extra dll in my msi file. Also it seems there are some typos
in the later actions in regards to $TheService>2 rather than =2 but maybe
this is correct?

2.       Run installutil.exe from the .net directory as suggested here:
http://www.dalun.com/wix/12.07.2006.htm but I am concerned about having to
worry about that program actually being there and wonder if this method
supports uninstall, commit or rollback.

3.       Ideally I would like to sort of self install by calling a class
method in my service assembly to instantiate the ProjectInstaller class that
is already defined and based on System.Configuration.Install.Installer that
was inserted into my VS service project and references the
System.ServiceProcess assembly. My understanding is this SHOULD be
everything I need to install my service if I can somehow call the code from
WIX. I think this is possible and wonder if this would be the best way to go
as long as I could have actions for supporting install, uninstall, rollback
and commit which I don't understand how WIX supports all that.

4.       Possibly use <ServiceInstall> something like this
http://avinashkt.blogspot.com/2007/05/how-to-install-windows-service-using.h
tml  if I could earlier run a custom action that looks up a registry entry
and decrypts it for the account and password and then set properties that
would be used by the <ServiceInstall> element account and password tags.
This CA would have to access my .NET code. And here also, I'm unclear about
how or if WIX supports the additional service actions of uninstall, rollback
and commit as they are not in this example but do seem to be in this one
http://blog.vagmim.com/2004/09/installing-windows-services-created.html
which seems much more confusing to me but is old so maybe wix3 does all that
automagically now.

 

I like idea #3 best only because there is some compatibility with the VS
service project as well as installutil and I already have the code there but
I don't know if that choice is possible or best practice.

 

Thanks for any suggestions and guidance to a WIX newbie, Dave
