Silent Installation and Silent Registration

[EViews Steve]

Did you manually uninstall EViews before attempting to use your silent install script?

No, we still need Eviews 12 version too.

The first time you run the EViews installer, it will install. The second time you run it, it will detect the previous installation and then try to run in uninstallation mode.

So using a recorded script for installation on a machine that already has that version of EViews installed on it will result in an error because the second time you run the installer it's trying to uninstall instead of install.

To test your script, manually uninstall that version of EViews from your test host first.
