Admin Console install fails with FileNotFoundException after uninstall with NAM 4.3

Running test Admin Console 4.3.1 server on SLES 12 SP2. To test a backup and restore disaster recovery scenario, an admin uninstalls the Admin Console component (uninstall option 1) before re-installing and restoring the backup. However, during the re-install of NAM 4.3.1, the following error is thrown before the install is aborted:

Installing the Novell iManager: failed
Error while installing iManager. Check the /tmp/novell_access_manager/install_iman_2017-06-08_17:37:53.log log file for more information.
Terminating Installation.

LinuxRemoveRegistry: Removing the InstallAnywhere registry file.

Uninstall the Admin Console with option 6 (forcefully remove all components)

The uninstall with option 1 does not remove a number of components - which causes the install to break. Uninstall 6 removes everything. The components that were not removed (shown below) can also be manually removed prior to re-installing.

novell-devman-doc-4.3.2.0-15
novell-devman-jars-4.3.2.0-15
novell-base-0.1.1-4
novell-jdk-1.8.0_131-1
novell-NOVLsubag-8.8.8.10-0
novell-edirectory-xdaslog-8.8.8.10-0
google-perftools-1.8.1-7.2
netiq-patchtool-4.3.2.0-15

NAM 4.4 will fix this issue.
