I downloaded 1.4.9.1 to slipstream the updates to bring XP Pro SP3 up to date. I start nLite (I'm running Vista Home Premium 64bit). It says "WElcome to nLite!..." I click "Next" and it asks me to tell it where the Windows installation is located. I don't know what it wants. I give it the path to my XP iso, no good, I give it the path to the mounted iso, no good, I give it the path to C:\Windows, no good. What path does it want? I don't remember doing this before in older versions.
