We had to workaround data_engine startup issues but once the data_engine was up after reinstall, we had to manually deploy all Primary hub packages. Therefore the uimhome page was not updated.
Here are the steps to rectify this issue with uimhome not getting updated due to our need to do a manual Primary Hub /UIM Server install:
1. On the Primary Hub, Rt-click and deactivate the wasp probe (save off the wasp.cfg)
2. Rt-click and delete the wasp probe from the Primary hub
3. Delete the wasp directory/folder and its contents from the Primary hub server (found under the <installPath>\Nimsoft\probes\service directory)
4. Deploy the latest appropriate version of the following packages for 23.4.4 in the following order to your Primary hub:
- wasp
- uimhome
- mps
- adminconsoleapp
5. Activate the wasp probe on the Primary hub and wait for it to startup
Hit the /uimhome page on the Primary hub and check the displayed version which should now be 23.4.4..
6. Drag and drop the robot installers, e.g., robot_aix, robot_rhel, robot_rpm, etc., to update the Installers referenced on the uimhome page, e.g., these links will be updated.

NimBUS Manager.exe has also been attached to this case for distribution or usage.
