fails at sqlnet on 8.1.6 install.. why??

Hi.. I am trying to install 816 version for win NT 4.0
and it fails at a point where it says installing sqlnet..(11%) of the cd (oracle enterprise manager 8i release 2).. Any idea??

Do you get an error?

No error. It just gives up.. I mean the CD installation (universal Installer disappears)..

Reboot the machine and retry. NT seems to give problems during installs.

I've had problems installing from CD/networks.
Try copying the CD to your PC...and install it from there....

Rebooting did not help, nor logging in as administrator and installing did not help either, but when i copied the entire cd into a new folder and ran the stuff again.. IT WORKED..
Thanks a lot for all your suggestions.
Spl. thanks to rgaskell..
