I installed v18.104.22.168 and rebooted, as per the instructions. I received an error message telling me that I had no DVD burner! The burner was displayed (and checked) in the Drives/Selection menu. The tooltip displayed: On: 0, Off:0, Empty: 0 I reinstalled v22.214.171.124 and got the same problem, until I again reinstalled, this time removing registry information and registering after install. Any idea why v126.96.36.199 doesn't like my Lite-On LH-20A1S12C?
