Hello Tony,
Resolve QuickBooks error codes -6190 and -816, start by using the QB Desktop Install Diagnostic Tool and QB File Doctor. If the issue persists, try restoring the company file on the two machines requiring simultaneous QB operation. Ensure that QuickBooks is updated to the latest version on both computers. Verify that all systems have the correct permissions to access and modify the company file. Additionally, check for any discrepancies in the file path or name. If the problem persists, consider disabling antivirus or firewall temporarily to rule out potential conflicts.
