Manual Patches for Ultima Online
These manual patches are zips containing all of the files that were changed. All you need to do is select which UO release you have, download, and extract these to your UO path replacing all files of the same name. This will easily patch your UO up to 4.0.2a(2).
Original (The First non-beta release of UO)
Renaissance (Includes install off of Third Dawn release)
*Although some of these manual patches contain a majority of UO's files, they will not be able to run standalone. You must have UO installed. Also, downloading a patch from a later release will only cause errors. they WILL NOT upgrade your UO release in any way. Only the version.
