Setup Files Corrupted

Trying to install the latest 5.89 update, I'm getting an error message dialog box that indicates "Setup files corrupted"

Any experience with this sort of thing from latest update or previous ones?

Might come from your anti virus program thinking that our program is infected (it's not) and aborts the download which results in a corrupted file. Turn your anti virus program off for a while (or get a better one instead) and try again.
