NotesSql changing "Using Installation" in ODBC

I have a couple of LN clients installed on my PC for testing of applications on different version.

Currently my NotesSQL is point at my 6.5.3 client, I would like to change it to use 7.0.1. How can I configure it so it points at the 7.0.1 folder?

I tried uninstalling and reinstalling. It seems pointing at 6.5.3.

Do I have to uninstall it, reboot, hide my 6.5.3 folder and reinstall and then hope it pickups up the 7.0.1. Or is there an easier way, a ini or cfg or registry entry I can change. (Incase I need to quickly change it back.)
