Nero 6.0: error 6 during installation

Dear friends,

I got Nero 6.0 suite OEM with a new DVD-burner. Unfortunately, during installation I get the following error message: “An error occurred during the copy process.Error 6.The handle is invalid.Please reboot your computor and retry”. (of course, after reboot, no change).

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 and INCD. :sad:
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 !
