Ok, so I have been trying to get Nero to install using opk and the [OemRunOnce] in winbom.ini. All works well except that OemRunOnce runs when WinPE is running. This makes Nero installation halt an claiming there is no windows xp installed, offcurse there isnt its winPE . So i tried using the [AppPreAPP01.Attach] instead. That works fine, it copys the files from the shared folder to the harddrive but it doesent install the application. What i can get from the opk chm file I need two winbom.ini files, that also works fine but i have to use a floppy after the xp installation is done and i run sysprep - factory. Isnt there some way to make this fully automated and eliminating the use of the floppy?
