The b install-packages will fail to reinstall 7zip if the registry contains a reference that the package is already installed.
In Regedit, open HK_CLASSES_ROOT\eDiscovery\Packages and delete the 7zip key before running install-packages.

This b command will re-install the 3rd party packages and resolve this issue. Verify by checking the contents of D:\eDiscovery Packages
** Note: D: is used as an example of the default eDiscovery install location, however it is possible from version 7.1.3 and later that another install location was used. Substitute D: with the correct drive letter in these circumstances.**
