I have the same problem of rikit with nero 6 suite OEM ! I uninstalled previous nero 5.5 and did not change the saving path during installation.
I only tried to set the win95 compatibility mode on the setup.exe: this allowed me to install nero burning rom but not many others like nerovision express 2.
Please note that the same installation cd worked perfectly on the other winME partition of the same pc.
my pc: pentium IV 2,53GHz, asus p4pe, 512MB RAM DDR333, HD Maxtor 80GB, Gainward Geforce4 Ti4200.
Thank you for any help you can provide !
