I bought four copies of Office 2003 (four boxes and disks). One of the four computers died. In checking to see which disk to install on the replacement computer, I discovered three of the computers (includes the dead unit) have the same product key, but different product IDs. With the install on the replacement computer, that will leave two computers with the same product keys. Is that an issue since I have four licenses, or do I have to re-install on one of the computers so that each computer has its own product key? Also, why would the product IDs be different? I posted this question before but cannot find it in the forum to see if there was a response, so forgive the duplication.
