did not work, support states its a microsoft issue.

I have SP1 installed. Level 2 Tech Support confirmed that my system has all the required components installed. They also performed all the necessary re-installs as well. The issue still persists with the same windows event monitor application error.

Thank you for bringing this to my attention, @ctc15.

I'm here to ensure QuickBooks Desktop Pro 2019 is installed on your computer and works. Let's get started!

Have you tried installing QuickBooks to a different device or computer? If not, I'd recommend doing so. This is for us to isolate the issue. If the application is installed on a different computer and works well, it means that the operating system of your current computer is already damage.

On the other hand, let's run the Quickbooks Component Repair Tool to Fix Microsoft .NET Framework, MSXML, and C++ issues.

Here's how:   

1. Create a backup copy of your company file.
2. Restart your computer before running the tool.
3. Close all programs.
4. Download the QuickBooks Component Repair Tool (All Windows Versions).
5. Double-click the file to run the program.
6. Restart your computer after running the tool.

Once completed, let's proceed with installing QuickBooks in Selective Startup. It will allow you to start Windows with only select items running on your computer.

Here's how:

1. On your keyboard, press Windows+R to open the Run command.
2. Type msconfig, then select OK.
3. In the General tab, select Selective startup and Load system services.
4. Go to the Services tab, then select Hide all Microsoft Services.
5. Select Disable all.
6. User-added image.
7. Unmark the Hide all Microsoft Services checkbox.
8. Check the list of services and ensure the Windows Installer checkbox is selected. If it is not, mark it then select OK.
9.  On the System Configuration window, select Restart.

If the Selective Start-up still does not work, let's do Super Clean install to completely remove QuickBooks from your computer.

Here's how:

1. Reboot your computer to close unnecessary programs.
2. Back up the Windows registry.
3. Uninstall QuickBooks Desktop.
4. Stop all QuickBooks processes such as QBCFMonitorService, QBDBMgr, QBDBMgrN, QBPESEVNT08R, QBW32, and QBWebConnector.
5. Rename all Intuit folders to intuit.old.
6. Edit the Windows registry.
7. After clearing the registry, reboot the computer to ensure that no QuickBooks DB services is running during the installation.
8. Download and install QuickBooks.
9. After installing the first version, make sure that you can Open the Database Server Manager (if you are at the server).

Once installation is complete, reboot your computer to ensure that all components are updated completely. After installation, register and activate QuickBooks and you’re all set.

If the issue persists, I'd recommend reaching out to our Technical Support Team. A specialist will be able to further check on QuickBooks via secured remote access session.

Here’s how you can reach them:

1. Visit: https://help.quickbooks.intuit.com/en_US/contact.
2. Choose the QuickBooks Product.
3. Select your QuickBooks Desktop version.
4. On the Contact Us page, select a topic.
5. Click on Get Phone Number button to see the support number.

juVielL,

Thank you for the detailed instructions, unfortunately the level 2 support team performed all of these actions (via remote desktop)  and the application still does not launch.

Yes, I installed the software successfully on a windows 7 VM running on the PC.

Ironically, other applications install on the physical PC (ie MS Office) without issues so I'm not sure if there is a windows system corruption.

Hi there, @ctc15.

It's time you got the help you need, and I'm the person to get you pointed in the right direction for determining why QuickBooks still won't launch.

I appreciate your efforts for following all the troubleshooting steps provided by my colleagues. Since the issue still persists, you need to get it touch back to our QuickBooks Desktop Technical Team. They have additional tools to pull up your account and send a request about this issue to a higher level of support (Tier 3) to investigate this further. 

You can contact them by following the steps provided by @juVielL and @Rose-A.
