What OS are you nLiteing and under what OS? Nlite 1.4.9.1 on XP Pro SP3 or Nlite 1.4.6.? on the same machine. (I updated after having the error the first time) What kind of source are you using? -- Vanilla XP Pro Cooperate SP0 I am not sure what Nlites issue was / is. After doing alot more working myself I found that If I try to do things in this order I get the error . Slip Stream SP3, Slip Stream IE7, Slip Stream WMP11.... HOWEVER if I do things in this order I do not get the error. Slip Stream SP3, Slip Stream WMP11, Slipstream IE7. Irregardless of the cause I at least got it to work.
