Below is a clear guide explaining the causes and step-by-step solutions to fix Error 5502.

QuickBooks cannot open the company file
Multi-user mode stops working

If these signs appear, follow the solutions below.
Solution 1: Verify Hosting Settings
Hosting should be enabled only on the server, not on workstations.

Go to File → Utilities
If you see Host Multi-User Access, click it
On all workstations, open QuickBooks
Go to File → Utilities
If you see Stop Hosting Multi-User Access, click it

Add .OLD at the end (example: company.qbw.nd.old)
Open QuickBooks again
QuickBooks will automatically create a fresh network file.

Security software may block QuickBooks communication.
Fix:
Add QuickBooks to firewall exceptions
Allow QuickBooks ports (depending on version)

If QuickBooks works afterward, add permanent exceptions.
Solution 5: Run QuickBooks Database Server Manager
This tool fixes network connection issues.
Steps:
Open QuickBooks Tool Hub
Select Network Issues
Click QuickBooks Database Server Manager
Scan the folder containing the company file
Restart QuickBooks services
Try opening the file again.
