So far the patching problem has only been reported to me as Win7. Anyone with other OS's getting it?

Fixes have been reported as:
reinstall Dom3 (deletes config? has anyone tried just deleting the config?)
or having Dom3 in a directory outside of the "Program Files" structure.
or (the official Windows answer) is that the exe needs to be run as Administrator

This is probably also true of Vista, and possibly Win8
