If the MSIHashTable does not get updated with new information for a newly updated file, will the file get updated during a patch?

We are creating patches like this, we have admin image of our 1.0 product, and then we copied this image to a new location, named 1.0a. We then copied over the updated files into the 1.0a location and edited the file versions in the File table.

For files that do not contain version information, do we need to update the MSIHash table in order for those files to get updated during a patch?

Thanks for you help.

Yes. If the has in the msi database matches the existing file on the user's machine, it will not be overwritten.
In general that adat in the .msi file should always match the actual file data, this includes hash and version numbers.
