I'm testing ERAS / ERAC and NOD32 on WinXP SP3 machines with Windows Installer 4.5. The problem I'm having is remote uninstallation of password protected clients. ##Parameters## NOD32: /UNINSTALL /PWD=""thepassword"" (2 sets of double quotes) ESS: qn! The uninstallation initiates fine, yet a message box displays "Enter a valid password to continue uninstallation" on the workstation. I have uninstalled through add/remove using the same password I supplied through the parameter. ##einstaller.log## Status 1012, ID 0: Failure during the package uninstall - exit code: 1603, additional code: 2, description: Fatal error during installation. Status 20006, ID 0: Service stuff cleanup finished with return code 0.
