Hello James, 

Can you try the following?

Close all the Ansys applications.

Go to Start>search “Product and CAD Configuration 2023 R1” and run it as admin.

Follow the below steps: (while configuring products and unconfiguring products “select all” option)

  1. Install Required Prerequisites.
  2. Unconfigure Products & CADs.
  3. Configure Products & CADs.

Rename the Ansys folder to Ansys.old (search %appdata% in Windows File Explorer search bar) and .ansys to .ansys.old (%temp%) 

Launch the application again.

Let me know if the above solutions work for you.
