Cannot clean up a server completely after uninstalling CA Service Desk Manager. Un-installation and clean-up in server registry and removing data from al_cdb_config tables still see a message that indicates that Search Server is already installed.

CA Service Management 17.0
Upgrade to 17.1
OS is Windows Server 2012R2
Cause:
Search server was not uninstalled in the right way for complete cleanup
Resolution:
Follow the below steps to resolve the issue

1. Enable the Folder settings to view hidden files if not already done 
2. Find folder "zero G Registry" under C:\Program Files 
3. Take a backup of this folder 
4. Delete the folder 
5. Run DBCleanupUtility once again 
6. Re-run the installation process to see if its resolved.
Additional Information:
Note: DBCleanupUtility will not uninstall Search server if you plan to clean up the environment. However, you may want to uninstall the application (Search Server) from Control panel.
