Sage 50 Error: 'Cannot Connect to Your Company Data Location'

Workstations trying to open a shared company file get “Sage 50 cannot connect to your company data location” instead of opening normally.

Why this happens

• The company data path changed (data was moved to a new folder or server) and workstations still point at the old location
• A mapped network drive is disconnected, unmapped, or pointing somewhere unexpected
• The shared data folder doesn’t have the right permissions for the Windows user account trying to connect
• A firewall or antivirus is blocking the ports Sage 50’s Connection Manager service needs
• The Connection Manager service on the server isn’t running
• A version mismatch between the server and workstation installations of Sage 50

Steps to fix it

1. Confirm the company data path in Sage 50’s settings actually matches where the data currently lives — re-point it if the data was moved.
2. Check the mapped network drive on the affected workstation is still connected and pointing to the right server/folder.
3. Verify folder permissions on the shared company data folder allow full read/write access for the Windows accounts using Sage 50.
4. Open the required firewall ports (13531 and 13540–13545) on both the server and workstations, or add Sage 50 as a firewall exception.
5. Confirm the Connection Manager service is running on the server — restart it if it’s stopped.
6. Match Sage 50 versions across the server and every workstation; update whichever machine is behind.

When to get help

Network and firewall configuration on a shared office server isn’t always something you want to troubleshoot solo, especially if other workstations are still working normally. Getting a second set of eyes on the server-side settings usually resolves this faster than trial-and-error on the affected workstation alone. Sage’s official Sage 50 support resources cover this in more depth.
