Firewalls can prevent QuickBooks from accessing the Internet properly and that is a major concern. Different firewalls may be installed on your computer but it’s not recommended to use more than one. Let’s take a look at how to make sure QuickBooks files are not blocked by Windows Firewall:

QuickBooks Desktop 2018: 8019, 56728, 55378-55382 QuickBooks Desktop 2017: 8019, 56727, 55373-55377 QuickBooks Desktop 2016: 8019, 56726, 55368-55372 QuickBooks Desktop 2015: 8019, 56725, 55363-55367

Solution 6: Perform a Clean Install of QuickBooks

A clean install is usually done when one of the program’s features are damaged and need repair and also when the usual reinstall fails to provide any comfort or a solution to the problem. In order to start the installation process make sure you have the setup file you downloaded from QuickBooks’ official site. You will also need your license number before you start.

The next thing in the process is to rename the installation folders so that QuickBooks does not use the remaining files after you reinstall it. This is an easy task. Note: If you are not able to see some of the folders we mention below, you will need to enable the Show Hidden Files and Folders option from within the folder.

C:\ProgramData\Intuit\QuickBooks (year) C:\Users(current user)\AppData\Local\Intuit\QuickBooks (year) C:\Program Files\Intuit\QuickBooks(year) 64-bit version C:\Program Files (x86)\Intuit\QuickBooks (year) Note: You may end up receiving the “Access Denied” error when you try to rename these folders. This only means that one of the QuickBooks processes is running and it prevents you from modifying any of the files and folders these processes are using. Follow the steps below to fix this:

QBDBMgrN.exe QBDBMgr.exe QBCFMonitorService.exe Qbw32.exe Alternative: If the clean uninstall doesn’t work for some reason, you can always try and repair the installation by choosing the Repair option in Step 7 of this Solution. After the process finishes, try to see if the error message still appears.
