Did *you* create the service, or did you copy and paste the code the
installer uses? I think this may be the issue if the former. erlsrv.exe is
used to start/stop/install/remove Erlang services from what I can tell. You
wouldn't want to add it yourself as a service to start; you'd want to use it
in cmd.exe to add a service and then start whatever it put in there.

Here's the config file for the installer (which I think is InnoSetup):

You should have installed the service by running erlsrv.exe with these
parameters (I filled in the variables from the ISS file, so change as
add "CouchDB" -workdir "X:\CouchDB\bin" -onfail restart_always -args "-sasl
errlog_type error -s couch +A 4 +W w" -comment "CouchDB 1.x.x"

Then you can either net start CouchDB, or the installer does erlsrv.exe
start "CouchDB".

I checked out the source for the Windows fork and grepped it for both "hkey"
and "hk", and nothing Windows-specific came out. I don't think that CouchDB
is your problem here. I think it's that Erlang is refusing to start because
it is not installed properly (and it may well depend on some sort of
registry entries). There might be a standalone version of Erlang that you
can extract to a folder and use, and then once that worked, you could use
that to install CouchDB as a service and run it.

It sounds to me like you're trying to make a version of CouchDB that is
batch file installable and survives a nuke and pave. But that's a guess; you
could be hooking up CouchDB to a missile defense system. In any event, help
us help you - try to explain why you can't use the installer in silent mode
and why you can't use registry entries.

P.S. In Windows, when you remove a service, you'll have to reboot to fully
be rid of its security descriptors and whatnot. Definitely don't try
removing/adding the service without restarting or you may be compounding the
problem by having incorrect SDs.
