We managed to find a solution, but it is a little bit complicated. Maybe there are better / easier ways to resolve the problem. Here is what we’ve done: We created a vbscript file that stops and uninstalls the service and added it to the package. Here is the code Option Explicit   On Error Resume Next   Dim objWshShell   Set objWshShell = CreateObject("WScript.Shell")   objWshShell.Run "sc stop <YourServiceInstanceName>",0,true objWshShell.Run "sc delete <YourServiceInstanceName>",0,true   Set objWshShell = Nothing Then we added to Text File Changes a replacement rule in order to replace <YourServiceInstanceName> with the specific service instance name. NOTE: This is a unique service identifier that you use. It may be different from service display name. After that we created a custom action to call the VBScript file and added it to Exec Sequence after InstallValidate with condition REMOVE=”ALL” In service definition in components > advanced we removed events to stop and uninstall the service, because now it is done with the script mentioned above. That’s important, because when uninstaller can’t find a service on uninstallation, it requires reboot. That’s it. Hope it helps. ... View more
