"A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file." when installing a program.

Emily Page asked on
I'm trying to install an application that came with 3 others on a disk. The other 3 installed fine but when I try to install this one (iom Grapher if you're wondering) I get the error mentioned in the title. The other three are games and this one is a grapher which records feedback from sensors you plug into the USB port.
I've restarted my computer, removed the disk and retried installing, nothing has worked. Help please?
