If you have installed any previous version of SQL Clone, here's the process to ensure it's fully removed:

• Remove all clones within the application, and deleting the folder "localappdata%\Red Gate\SQL Clone\clones"
• Remove all images within the application, and deleting any files left on disk
• Uninstall the old version
• Remove SQL Clone certificates:
  •  Using the Windows Certificates snap-in, they are under Local Computer > Personal > Certificates and called 
    • “SQL Clone Server” (or “SQL Clone Management Service for Agents” prior to version 0.8)
    • “SQL Clone Agent”
• Drop the SQL Clone Configuration database created by the server to hold all its configuration (called 'SqlClone_Config' by default)
• Remove the "settings.json" file under "%allusersprofile%\Red Gate\SQL Clone Agent" folder
• Reboot the machine
• Ensure that there are no services called "SQL Clone Server" or "SQL Clone Agent"
• Delete any agent installer exes you had downloaded - they will not work with any other installation and could cause confusion
