I am trying to install centos 5.5 x86_64 through netinstall .I downloaded the iso and burned to a CD/DVD. Then I tried installing through HTTP.

Web site name:
CentOS directory for x86_64: /centos/5.5/os/x86_64

Everything went fine until Installation .it said Installation may take several minutes. Please wait . Then it started throwing error saying device-mapper1.02.rpm cannot be opened etc.And when i retry, the window saying the message "Starting install process this may take several minutes" is stuck for long duration .

Am i doing something wrong ??

See: CentOS 5.5 remote kickstart installation stalls at "Starting install process." How to debug?

Maybe try another CentOS mirror for the installation. Search for one close to your location. It could be a firewall issue as well.
