I am running into an issue where my service upgrades are no longer upgrading. It is going through the process, I can see it uninstall, remove the service, it then puts back all the files except for my service executable and the service in Windows. I've been using this for a while and haven't had an issue until now, so I'm not sure what I have done.
I've attached the installer log files but replaced a lot of the words in it to hide some information. The install is set to start/stop on install and stop/delete on uninstall. The upgrade code remains the same but the product code changes with each new version. It is set to automatically upgrade and to uninstall first then install the new version.
