Product Key Issue

[jvcupo]

During re install, Office Mac 2008 asks for 25 character product key but my key only has 20 characters. On my disc it says : xxxxx-xxx-xxxxxxx-xxxxx.
The program will only take 5 characters and automatically puts in hyphens What gives? Program has been running on three macs for years perfectly

I have Office: mac 2008 Home&Student Edition. Each of my three product keys has the form XXXXX-XXXXX-XXXXX-XXXXX-XXXXX, where each X is an number or uppercase letter. These keys are on bar-coded labels, not on the disk itself.
