QUICKBOOKS PRO 2020 WONT OPEN EVEN AFTER RELOAD AND ALL RECOMMENDED TESTS...SAYS OPENING THEN GOES AWAY

Disconnect your internet connection. They try running your QB Desktop program again. Did you encounter the same issue?

Thank you for dropping by the Community today, TBAR1. 

Let's go over some troubleshooting steps together so you can open QuickBooks Desktop (QBDT) seamlessly. I'm here to guide you through the steps to carry out these tasks.

We can start by suppressing the QuickBooks program. This prevents it from opening any company file automatically. 

Here's how:

1. Hold down the Ctrl key and double-click the QuickBooks Desktop icon.
2. Continue pressing the Ctrl key until you see the No Company Open window, QuickBooks freezes or gives you an error.
3. Select the company file you're working on and click the Open button. 

If you continue to get the same result, download and install the QuickBooks Tools Hub. This utility can fix common errors you encounter in the program.

To launch the tool: 

1. Make sure to close your QuickBooks.
2. Then, download the latest version of the QuickBooks Tool Hub (1.6.0.5)and click Save File.
3. Open the QuickBooksToolHub.exe link.
4. Follow the on-screen instructions to complete the installation process.
5. Next, double-click the icon on your desktop to access the tool.
   
   

If the issue persists, perform Solutions 2 up to 5 in this article: QuickBooks Desktop won't open. If you wish to upgrade to a newer version of the program, you can go over this guide to learn more about the process: Upgrade QuickBooks Desktop Pro Plus, Premier Plus, or Enterprise.

Utilize these resources in the future if QBDT stops working or you can open the company file:

No luck....same as before....says opening for about 3 seconds then goes away...thank You for your help

Tried all that, same ....still starts to open then goes away....

Login to your CAMPS. Can you find your license code there?

Try to reinstall your QB.

I did reinstall the software from the download on my intuit account...still no change. Thank You

I did reinstall software....no change

Consider to install the trial version of QBD 2021 Pro to isolate the problem. If the same error persists, the problem is on your machine.

I know how beneficial it is to have QuickBooks Desktop running, @TBAR1. Let's make sure you'll get the information you need. 

QuickBooks Desktop (QBDT) Pro 2020 will be discontinued in QuickBooks on May 31st, 2023. There may be a software issue since the update is no longer available on this version.

 I would recommend consulting with your IT department about the issue if you still can't open with your QuickBooks Desktop Pro 2020. If the same issue persists, I suggest upgrading your QuickBooks Desktop version. Otherwise, you'll want to move your QuickBooks Desktop to QuickBooks Online and experience a more flexible, secure, and up-to-date platform for your books.

For more information on this discontinuation and migration process, please make sure to check out the following resources listed below:

• QuickBooks Desktop 2020 service discontinuation policy
• For the full list of subscription features, check out the QuickBooks Online pricing page.

Try opening the company working file (.QBW) from its saved location.  That works for me when QB randomly does that.
