If you encounter this error when installing or updating TSplus:
Check your connection and click 'Retry' to try downloading the files again, or click 'Cancel' to terminate setup.
(Omniware is a rebranded version of TSplus - exact same code as TSplus)
Then you need to check this GPO and reboot the server:
Deploy a Group Policy Object to the client to turn off Automatic Root Certificates Update.
To do it, follow these steps on a Windows Server based server:
- Open Group Policy Management Console.
To do it, hold the Windows key and press the r key.
Type Gpmc.msc in the Run box, and then select OK.
- Create a new Group Policy Object (GPO)
or select an existing Group Policy Object (GPO) to change.
- Right-click the selected Group Policy Object (GPO)
and then select Edit and browse to the following Group Policy:
Computer Configuration > Administrative Templates > System > Internet Communication Management > Internet Communication settings
- In the details pane,
double-click Turn off Automatic Root Certificates Update, and then select Enabled.
Correcting this GPO allows AdminTool to be able to query TSplus servers.
