***Hofman (cmhofman)** [reported (on Launchpad)](https://bugs.launchpad.net/sparkle/+bug/401437) on' 2009-07-19:*

When the final installation fails (copying the new version to the
install location), the old version that was moved to a temporary
location should be moved back to the old location so the user can easily
find it back. This problem can happen when the /Applciation/ folder is
password protected.

I'm passing on a problem reported by one of our users, who reported:

"When the application folder is password protected, and one updates to
the new version, it does not ask for the password, but reports that the
update has failed. Then the current version is already erased."
