Downgrades are not supported. For example, if HP ESO 3.5.0.0 is currently installed, and you
try to install HP ESO 1.0.0.0, 2.0.0.0, or 3.0.0.0, you will see a warning screen as shown in
Figure 6 (page 13) . If you attempt to continue, you will see an error screen.

Silent installation
HP ESO can be installed in silent (non-interactive) mode by adding the /s or /silent switch to
the installer package's executable file, such as cp018233.exe /s when executing. When silent
installation is performed, HP ESO will be installed to completion without any user interaction.
NOTE: During silent installation, the prerequisite Microsoft SQL Management Object package
will be installed automatically if it is not installed in the system. To prevent this from happening,
extract the installer package into a temporary folder by clicking Extract during installation. At the
location of the extracted files, delete SQL_AS_AMO.msi, SharedManagementObjects.msi,
and SQLSysClrTypes.msi, and then execute cpqsetup.exe.
