I tried installing using those files and I didn't get any message or problem, so there's some piece of the puzzle that's different. What is the exact size (in bytes) of the frm file you are using? The size should be 45,214,387 bytes. If you happened to get a corrupted frm file that is significantly smaller than this size you may get that error message.
Would you also please give more detail as to your setup... are you upgrading from a previous version; what OS, and configuration are you using; and any other detail you can offer.
Thanks,
