    copied!<p>We have many questions on stackoverflow regarding uninstallation of Windows Service.<br/> After trying all of them I still fail to uninstall the windows service on new version Installation.</p> <p>I use setup and deployment project to install/uninstall my project which has a windows service and some other projects.</p> <p>During installation of newer version, all other projects are successfully re-installed but windows service project fails to Re-install and says: </p> <blockquote> <p>Error 1001: The specified service already exists.</p> </blockquote> <p>I referred <a href="https://stackoverflow.com/questions/451573/how-do-i-eliminate-the-specified-service-already-exists-when-i-install-new-vers/617385#617385">this link</a> and tried to add code to my Install custom action to Stop the service. If I understood the answer in this link correctly, I have put the code to stop the service inside projectInstaller.cs file of the Service:</p> <pre><code>public override void Install(IDictionary stateSaver) { ServiceController sc = new ServiceController("SareeManagerNotifications"); if (sc.Status == ServiceControllerStatus.Running) sc.Stop(); base.Install(stateSaver); } </code></pre> <p>Custom action pane looks like: <img src="https://i.stack.imgur.com/9nXPp.png" alt="enter image description here"></p> <p>Where the highlighted part is the Service.</p> <p>I also went through <a href="http://social.msdn.microsoft.com/Forums/en-US/winformssetup/thread/bedbb8bd-dad5-4bcb-a87a-ac69386669b4/" rel="nofollow noreferrer">this answer</a> which says to set custom action condition as <br/><code>NOT PREVIOUSVERSIONSINSTALLED</code>.</p> <p><img src="https://i.stack.imgur.com/kRucP.png" alt="enter image description here"></p> <p>This doesn't work for me. Where am I going wrong ?</p> <p>Thanks in advance :)</p>
