Been happily running with 4.2.40 for quite a while now on W7 64. Downloaded the 4.2.58 installer and intended to do an upgrade on the installed version - process comes about halfway and then pukes with the attached message .................. Now the problem: 1. This machine already ONLY runs with the actual ADMINISTRATOR account with full administrator rights and 4.2.40 was installed by Administrator 2. So how do I give it sufficient privileges? 3. After canceling out of this and restarting the system, I am no longer able to uninstall the current installed and running version - I am told that the ESS uninstaller in the programs list is only valid for installed components. Any idea if something is corrupt here and how to go about solving this?
