@Acheron, thank you! What version of VCRedist was merged? 2005 or 2005 SP1? I read on some russian forums about previous version of Lite that sometimes peoples plays with reinstalling of NET 2.0, fixing of VCRedist or something around gdiplus for Lite installation problems resolving. And on 1 comp of 3 I had same troubles too. Only after reinstalling of VC 2005 SP1 and + (!) fixing it (by right mouse button -> fix) Nero Lite becomes workable on this one machine. I don't know why. PS In next message prezioso00 have same error for Vista. @prezioso00, What files failed to register? NeroFileDialog.dll, CoverEdCtrl.ocx and NeroDigitalExt.dll?
