I experienced the problem of win-aspi ?.? file missing after I reinstalled my win nt.
I searched for the file winaspi32.dll and found it in the winnt folder ,I then moved it to the folder ahead but no success.Even after installing nero I couldn't find the win-aspi file in the temp folder but couldn't find it.
