SAP settings are sometimes controlled by Group Policy objects as well. Below are the troubleshooting steps/solutions you can try:

1. Ask your Org. admin for a specialized GPO for SAP installed machines where the Robot runs.
2. If there is no GPO make sure to edit the registry during the automation
3. If the options 1 and 2 are not possible, then using ABAP will also work.
4. Automate SAP using SAP BAPI (System user is enough you wont even need a dialog user with the right permissions/access level)
5. Check the local SAP config files while setting up SAP (In the config files the default might be to enable them when SAP restarts or periodical reset)

let me know if none of the above work. post the screenshots of your config/registry etc and we can see what else can be done.
