Hello WilliamSeitz,
Since this is an issue with a specific application, it would be recommended that you post your question or issue directly to a Forum or Support of that software manufacturer for Fidelity Active Trader Pro.
On my side, I can suggest that this kind of applications usually access a web service or API to retrieve information and sometimes these URLs may change, and the software needs to be updated or reinstalled in order to have the latest access configuration.
From Windows perspective I can recommend:
- Reinstall the application (as Administrator) in the first user session
- Disable proxy settings on the affected user if any
- Clear cache and cookies from your default browser
- Run an image repair (recommended to run using a downloaded image, mounted) https:// docs. microsoft. com/en-us/windows-hardware/manufacture/desktop/repair-a-windows-image?view=windows-11
- Cleanup the WinSxS folder: https:// docs. microsoft. com/en-us/windows-hardware/manufacture/desktop/clean-up-the-winsxs-folder?view=windows-11
- Run a clean boot to discard 3rd Party tools interfering on that session: https:// docs. microsoft. com/en-us/topic/how-to-perform-a-clean-boot-in-windows-da2f9573-6eec-00ad-2f8a-a97a1807f3dd
