This Installation cannot be launched by itself"" while trying to install eFiling on a Windows 7 workstation (running MAS 4.5). AV is disabled, UAC is off, Firewall is disabled. Can't get it to install. Oddly, before all the disabling, could not get the efiling install to run from either wksetup autorun or the 4.5 installer. Downloaded the installer from Aatrix. It starts to go, then gives the message. Have Sage on the line - stumped the first level guy - he's going for help. Anyone had this experience?
