If you downloaded the hotfix separately on each machine then maybe one of them is not complete as Eduardo suggested.
If it was the same download that you transferred between machines then that is a mystery.
Try copying the hotfix from the machine that worked to your other one rather than re-downloading it (if that is not what you have done already).
