Nero not getting installed on windows 2000


I recently upgraded my system to windows 2000 from windows 98. When I try to install Nero Express, it aborts saying “The wizard was interuppted before Nero- Burning Rom could be completely installed.Your system has not been modified. To complete the installation at another time,please run the setup again”. But I am able to install Incd though.

The software I have came along with the cd writer. I meet all the requirement specified in the manual too.

My sysem is Pentium 3, 450 M Hz, 128 MB ram, 6 Gb hard disk.
Windows 2000 - sp4

I am unable to identify the problem. Could any help regarding this? I did mail Nero too, but I ahve no response from that end.
