#1 - do not install this update, only errors upon installation
If u some how feel the need...
#2 - backup all db prior to stopping server
#3 - make a copy of the FM server folder prior to updating as u will need the old version once u screw it up with the updater

if u trash the new updated FM config and/ot folder, and use the old one. all should be ok. if a db wont start, use the most recent backup which i told u to do.

BIG TIP: DO NOT INSTALL!! I have no idea what the heck filemaker was thinking or if they tested it at all.
