Solution 2: Consult with your IT professional
Perform this step only if you are aware of the process and steps of configuring firewall, antivirus and other third party programs. If you require assistance for this, you can consult with our certified QuickBooks ProAdvisors or talk to your IT professional.
Sometimes default setting of systems and antivirus security which is set by the user for Internet security and firewall may stop and prevent the QuickBooks or other important components from downloading the updates as they might consider them as a threat or malicious file. So here, you need to recheck your settings and validate that is not the case.
What steps you should take for this?
- You need to verify the configuration of your Internet security and personal firewall software settings
- Ensure that the Ports 80 and Port 443 must be enabled, and the access must be provided to the following files
AutoBackupExe.exe | Dbmlsync.exe | QBDBMgrN.exe | FileManagement.exe |
DBManagerExe.exe | QuickBooksMessaging.exe | IntuitSyncManager.exe | FileMovementExe.exe |
QBServerUtilityMgr.exe | QBDBMgr.exe | QBCFMonitorService.exe | |
QBLaunch.exe | QBGDSPlugin.exe | QBW32.exe |
