Well, actually, you don't.

7.4.x is an entirely new install that imports the forums/users from your 6.5.5 database, so the error is not in the way of the upgrade path.
Thank you for responding. I still have this innate urge to fix the problem, but if no one posts a helping suggestion here, then I will fall back on your recommendation. Thanks.
