Unable to install 6.0.9, on our server 2008. Some error with the database. The install process failed at the database tuner stage.
Carlos at Guardian Angle support could not get it to work also.
Carlos tried to revert us to 5.1.7, but unable to restore to our original state. We have a local backup and AC remote backup. After a few hours of uninstalls and reinstalls we are still stuck. Developer is to call this monday to try to get us up an running.
We have updated 4-5 times over the last few years and fortunately have never had a major issue with installs, until now.
We are out of luck until this gets resolved. Will be using paper tomorrow morning. At least I printed out the monday's schedule last friday.
You might not want to jump in yet if you are not prepared to deal with potential hiccoughs like this.
