Upgrading issue to 4.2.3

[kooley2]

In order to solve a different issue (dialog boxes asking everyone to stay or leave) I tried upgrading from 4.2.2 to the latest version.

I followed the following procedure:
Upgrading from vBulletin 4.x.x
1- Close your board via the Admin Control Panel.
2- Delete install/install.php from your upload directory
3- Upload all remaining files from the 'upload/' folder in the zip.
4- Open your browser and point the URL to your forums, e.g. http://www.example.com/install/upgrade.php (where www.example.com/ is the URL of your vBulletin). Make sure to upload the files into your previous installation directory as appropriate (e.g. /forums/). The Upgrade Wizard will determine your vBulletin version and jump forward to the appropriate upgrade step.

I uploaded all the files - but when I try step 4, it doesn't seem to move the process forward....it just redirects to the (unupgraded) forum.

when I try to access admin CP I get this:
Security Alert!

The /install directory still exists.

This poses a security risk, so please delete that directory immediately. You cannot access the control panel until you do so.


Please dear people, any insight on what is going on - how do i move forward?

many thx!
