1. download the new version of nimldr792.tar.Z and install_LINUX_23_64.zip from this article. (This package installs robot 7.92GA.)
2. On the Linux box enter these commands to kill and remove the current robot:
rm -rf /opt/nimsoft/
3. use the new nimldr and install_LINUX_23_64.zip to reinstall the robot. When nimldr asks "Do we have a copy of the installation file locally?" say yes, and provide the path to this install_LINUX_23_64.zip file.
This will install the robot correctly and you will now be able to upgrade it and/or deploy probes successfully.
