I always set my SB install files to overwrite existing installations,
and backup replaced files.

Last night I applied an update in error, and decided to rollback that
update to a previous version. This is not something I do very often, in
fact I've probably not done this for years, but I seem to recall being
presented with a list of previous versions that I could rollback to.

Last night, I only had the option to uninstall, which removed
everything, including my backup files.

No harm done, as I had backups and previous versions etc. but I
wondered if I was missing a setting somewhere that would allow me to do
this in future.

Regards,

Neil.
