Unfortunately, updating Product A isn't an option. I could continue the 
practice of using a CA until Product A is retired and removed from the servers 
but I was hoping for a better option.

Would it be possible to release upgrades for both products with the
Event Sources authored? That way you can uninstall both.

Subject: [WiX-users] Permanent vs. SharedDllRefCount vs. better idea?

Hey all,
  Trying to clean up a mess of sorts. Product A was installed on a bunch
of servers long ago. Product A didn't create some EventSource entries so
somebody manually added the missing items on each server. Product B came
along and lives side by side with A. B is a old vdproj and it added the
EventSources via a custom action (aka still no component) so a manual
post fix was no longer required.

Now, I'm trying to upgrade Product B (Major Upgrade) and do it with Wix
(call it B.Wix)

I can have B.Wix create a permanent component so A will continue to work
after B.Wix is uninstalled (really while B is being upgraded). Is it
possible to uninstall it someday once A finally dies? According to the
docs, it does seem permanent is permanent and can't be altered
afterwards to not be.

So, can I cheat a little bit by using SharedDllRefCount to fake that A
is using it? The idea being B.Wix installs an adds an extra reference
count and then when A retired, I can decrement the count somehow and
then uninstall B.Wix and have the component uninstall. Would that work?
If so, how to decrement the reference count?
