v2.4.4 install error message

edit

I have down loaded the beta and standard versions twice each and get the following message each time.

bzip2: Compressed file ends unexpectedly; perhaps it is corrupted? Possible reason follows. bzip2: Inappropriate ioctl for device Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted. You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover data from undamaged sections of corrupted files. Unexpected EOF in archive Error is not recoverable: exiting now

what am i doing wrong . Using Centos 6.3 for 64 bit machine.
