Hi,
Currently, Wordfence is not supported on Windows hosts, though we've heard of quite a few people running it successfully.
In this case, it looks like the problem is that Windows converts all table names to lowercase, while Wordfence uses mixed-case table names. We do have an open feature request to possibly support all lower-case table names in a future version, but I don't have an estimate of when or if that may be implemented.
