Yes I've done thats... But I put the regtweaks to the oobeSystem, so it's good now. But I've a new interesting error. My post installer software install a lot of programs. Thats installer filtes are msi or install shield exes, but when the installing is done, I can't start the msi or install shiled installers... Very interesting that my xp, do this error. I've the most new NOD32.. so I think it can't be virus.
