Hi All, first post on this forum I have builded an unattended xp pro sp3 corporate dvd with nlite + driverpacks + WPI (all latest versions) its working great except by a few little problems: .- The "cd eject when done" feature seems that doesnt works on xp, I have installed more than 20 pcs and none eject the cd tray when wpi finishes, not a big deal otherwise .- At first I used the nlite "runonce" method to lauch WPI, but for some reason WPI crashes with some packages like netFXAIO a (1,2,3,3.5 .net framework installer) or a ninite installer , give me an "error 70:, c:/history.js, permission denied", I see this occur several times, so I swith to the $OEM$.rar method, when using "$OEM method" the "error 70" never happens. PD: Error 70 only happens when WPI starts launched by "nlite runonce" when launched manually never happens. .- But today WPI refuses to start automatically with a "Windows cant find I:/wpi/wpi.exe" seems that RunWPI its trying to find WPI/WPI.EXE on the latest removable letter (I:) but CD drive is "E:", the computer have the following drives: hard disk: C:/D: (partitions) cd drive: E: card reader: F:/G:/H:/I: .- On some situations seems that %sysdrv% isnt working, like FILECOPY commands, using %systemdrive% works fine, havent tested this much. Any help would be appreciated. PD: Sorry for my bad english. Regards.
