but when I start installing it I see this message after verification of the library and confirmation of the package to install:

You appear to be installing packages on a platform different
than the platform for which they were built.

This platform is CentOS5_64
Packages found: RHEL5_64
This may or may not work.

Installation can not continue without manual override.
You can override this safety check with ./install.sh --platform-override

WARNING: Bypassing this check may result in an install or
upgrade that is NOT usable.
