Error when installing need help!!

Everytime i try to install Flight simulator x I get an error message saying
Error 1335: The cabinet file required for this installation is corrupt and cannot be used. This could indicate a network error, an error reading from the CD-ROM or a problem with this package.
If someone could help me that would be great, I have windows xp.
