I have upgraded robots to version 7.93hf5 using the robot_update 7.93hf5 available on the CA Unified Infrastructure Management Hotfix Index. The upgrade was successful on all platforms except for 32 bit systems. When I deploy the robot_update on 32 bit systems I get the error: Distribution fails with: "No Sections found which can be installed on .."
If you have downloaded the patch before the September the 6th 2018 you have downloaded the first release available (build 9817). That build supports 64bit systems only.
UIM 8.x 32 bits platforms
On September the 6th a new build has been uploaded to the CA Unified Infrastructure Management Hotfix Index. The new build (build 9891) includes support for both 32bit and 64bit systems.
