I had a similar situation, where i to needed have a previous service, and an updated service running side by side on the same server. (It was more than just a database change, it was code changes as well). So I couldn't just run the same .exe twice. I needed a new .exe that was compiled with new DLLs but from the same project. Just changing the service name and display name of the service did not work for me, I still received the "service already existed error" which I believe is because I am using a Deployment Project. What finally did work for me is within my Deployment Project Properties there is a property called "ProductCode" which is a Guid.

After that, rebuilding the Setup Project to a new .exe or .msi installed successfully.
