installation problem

[cd75]

Hi, I don't have enough experience to understand the philosophic meaning of the error message I obtain when I'm installing ifc. It is:
RPM shows no Intel packages as installed.

Which of the following would you like to install?
1. warning: Expected size: 23211567 = lead(96)+sigs(100)+pad(4)+data(23211367)
warning: Actual size: 19845632
Intel Fortran Compiler for 32-bit applications, Version 7.0 Build 20021028Z
x. Exit

I have tried to install ifc on two different computers and I have obtained the same message in the two cases and the same Actual size. I have more than 1GB free space on both computers. I don't understand what I have to do. Is someone able to help me?
Thanks
CD

I suppose that you should check the size of your downloaded tar file against the original, and make sure that you are downloading in binary mode, if you are using software which deals with Windows text files.
