Enterprise Console RMS not supported

HI uri, 

Hope the steps below would resolve your issue. 

1. If running an unsupported version, check the release calendar for information on the release dates for the version that supports TLS 1.2. Until the release, Sophos Enterprise Console from version 5.4.1 cannot be installed.
   
   For more details, see Sophos Antivirus: version release dates in the Related Information section.
   
   
2. If you're running an unsupported version, but still want to install Sophos Enterprise Console from version 5.4.1. For example, the managed computers are no longer required, you will need to delete the computers from the Endpoints view:
   
   
   1. Right click an individual computer and select Delete.
      
      or
      
      
   2. Select multiple computers, right click and select Delete.
      
      Note: To determine the version of Anti-virus installed on the computer/s you want to delete, select the Anti-Virus Details tab.
