Program install error: A file that is required cannot be installed because the cabinet file setup has an invalid digital signature

Original title: Cabinet file setup 11.cab has an invalid digital signature.

When trying to install a software programme on my Windows 7 Netbook, an Installer Information Panel stated "A file that is required cannot be installed because the cabinet file setup 11.cab has an invalid digital signature. This may indicate that the cabinet file is corrupt". Thus the programme would not load. Is the problem with the software or with the Windows 7 Netbook? If the Netbook is the problem, can the faulty cabinet file be removed and replaced with a correct file? If so, how? Please help. Thank you.
