I previously was able to install/uninstall my windows service using the setup project within VS (C#). Recently, however, the install fails, and the message is that the "source <app name> already exists on the local computer".

If I try to uninstall, it tells me "The specified service does not exist as an installed serivce".

I have also tried this with the installutil from the command prompt, with the same results.

I found some references to my application in the registry, but have not tried to delete them all for fear of really messing things up.

I did see in the registry a 'Legacy_myapp', was able to delete it, but next time I tried the install, it was right back in the registry.

In my app, I write to the Event Log also, and don't know if this is causing some of my problems. (items in the registry that aren't cleaned up)

Please, any suggestions?
