Issue/Introduction

Customer ran the UIM server upgrade to UIM 20.4 and it was successful. But during the Operator Console upgrade to 20.4 when the OC Robot system requirements were checked, Disk Free (MB) displayed as 0. This is wrong. There is plenty of space on every drive on the OC Robot system and it is certainly not 0. There is no issue with cdm 6.84 which is up and running and collecting data on the OC Robot system.

The selected robot does not meet the minimum requirements for Operator Console.

 

 

Environment

• Release: 20.4
• Windows 2016, 2019

Cause

• lowercase versus uppercase drive in path within Windows registry

Resolution

When the OC installer (oc-installer-20.4.0-windows_x64.exe) was run, a 'non-default' drive:path was selected for the installation via the Browse button.

For example instead of C:\Program Files (x86)\Nimsoft, D:\UIM was selected.

To workaround this issue, we had to take the following steps:

1. Edit the Windows registry, navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NimbusWatcherService

2. Change the lowercase d in the path to Uppercase D.

d:\UIM\binimbus.exe

to...

D:\UIM\binimbus.exe

3. Then restart the robot.

4. Then, rerun the oc installer and it will display the correct Disk Free (MB) value.
