Update error... help needed

Reinstalling over an old install does not delete any added files. You do not need to uninstall first, just reinstalling is sufficient (in my experience, at any rate).

Another thing to watch for:

If you have multiple installs of SE IV, the patch may have a hard time finding the correct folder. Check to make sure it's looking in the right place.

If you need to change the target folder, you have to double-click the new folder in the list.
