title: the installed product does not match the installation source(s) error when uninstalling a windows service
body: <p>when I try to uninstall a windows service from the control panel, I am getting error "the installed product does not match the installation source(s), until a matching source is provided or the installed product and the source are synchronized, this action cannot be performed". actually I do have the original MSI file, but I modified some settings in the config file (where it is installed) after installation, so that might have caused it, how can I uninstall it now?</p>
