Layton ServiceDesk - Installation - Clean Reinstallation
From Layton Support
If for any reason you need to re-install Layton ServiceDesk on a separate computer, you can use the Connect to Existing Database option to connect to your existing Layton ServiceDesk database. This will not overwrite any database. If you need to reinstall, you will not lose any form designs or login screen layouts as these are stored in the Layton ServiceDesk database.
